An creat beatha sindiciúcháinLink to this heading#

\n

<4287>Tagann Django le creat ardleibhéil giniúna sindiúcháin beatha chun fothaí RSS agus:rfc: Atom a chruthú.

\n

Chun aon bheatha sindicíochta a chruthú, níl le déanamh agat ach rang gairid Python a scríobh. Is féidir leat an oiread fothaí a chruthú agus is mian leat.

\n

Tagann Django le API a ghiniúint beatha leibhéal níos ísle freisin. Úsáid é seo más mian leat fothaí a ghiniúint lasmuigh de chomhthéacs gréasáin, nó ar bhealach eile ar leibhéal níos ísle.

\n

Soláthraíonn an creat giniúna beatha ardleibhéil ag an rang:class: ~django.contrib.Syndication.Views.Feed. Chun fotha a chruthú, scríobh a:class: ~django.contrib.syndication.views.</topics/http/urls> feed aicme agus cuir in iúl ar shampla de i d:doc: URLConf.

Ranganna FeedLink to this heading#

\n

A: Class: ~django.contrib.syndication.views.feed aicme Python é rang a léiríonn beatha sindiciúcháin. Is féidir le beatha a bheith simplí (m.sh., fotha “nuacht láithreáin”, nó fotha bunúsach a thaispeánann na hiontrálacha is déanaí de bhlag) nó níos casta (m.sh., fotha a thaispeánann na hiontrálacha blag go léir i gcatagóir áirithe, áit a bhfuil an catagóir athraitheach).

\n

Ranganna beatha fo-rang:class: django.contrib.syndication.views.feed. Is féidir leo maireachtáil áit ar bith i do bhunachar cóid.

\n

Is tuairimí iad cásanna de:class: ~django.contrib.syndication.views.feed ranganna is féidir a úsáid i d:doc: URLCon</topics/http/urls> f.

Sampla simplíLink to this heading#

\n

Déanann an sampla simplí seo, tógtha ó shuíomh nuachta buailte póilíní hipitéiseach cur síos ar bheatha de na cúig mhír nuachta is déanaí:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.urls import reverse\nfrom policebeat.models import NewsItem\n\n\nclass LatestEntriesFeed(Feed):\n    title = "Police beat site news"\n    link = "/sitenews/"\n    description = "Updates on changes and additions to police beat central."\n\n    def items(self):\n        return NewsItem.objects.order_by("-pub_date")[:5]\n\n    def item_title(self, item):\n        return item.title\n\n    def item_description(self, item):\n        return item.description\n\n    # item_link is only needed if NewsItem has no get_absolute_url method.\n    def item_link(self, item):\n        return reverse("news-item", args=[item.pk])\n
\n

Chun URL a nascadh leis an bhfotha seo, cuir sampla den réad Featha i d:doc: </topics/http/urls> URLConf. Mar shampla:

\n
Code
from django.urls import path\nfrom myproject.feeds import LatestEntriesFeed\n\nurlpatterns = [\n    # ...\n    path("latest/feed/", LatestEntriesFeed()),\n    # ...\n]\n
\n

Nóta:

\n\n

Tá rud amháin fágtha le déanamh. <link><description>I bhfotha RSS, tá ``, ``<item>, agus ```` <title>` ag gach ``` ``. Ní mór dúinn a insint don chreat cad iad na sonraí atá le cur sna heilimintí sin.

\n\n
\n
\n

Sampla castaLink to this heading#

\n

Tacaíonn an creat le fothaí níos casta freisin, trí argóintí.

\n

Mar shampla, d'fhéadfadh suíomh Gréasáin fotha RSS de choireanna le déanaí a thairiscint do gach bualadh póilíní i gcathair. <dry>Bheadh sé amaideach rang ar leithligh: class: ~django.contrib.syndication.views.feed a chruthú do gach bualadh póilíní; a sháródh sé prionsabal: ref: DRY `agus chuirfeadh sonraí a cheangal le loighic cláraithe. Ina áit sin, ligeann an creat sindiciúcháin duit rochtain a fháil ar na hargóintí a rith ó do: doc: `URLConf </topics/http/urls> ionas gur féidir le fothaí míreanna a aschur bunaithe ar fhaisnéis i URL an bheatha.

\n

D'fhéadfadh fothaí buailte póilíní a bheith inrochtana trí URLanna mar seo:

\n\n

Is féidir iad seo a mheaitseáil le a: doc: URLConf líne mar </topics/http/urls>:

\n
Code
path("beats/<int:beat_id>/rss/", BeatFeed()),\n
\n

Cosúil le dearcadh, cuirtear na hargóintí san URL chuig an modh ``get_object () ``in éineacht leis an réad iarratais.

\n

Seo an cód do na fothaí seo a bhaineann go sonrach le bualadh:

\n
Code
from django.contrib.syndication.views import Feed\n\n\nclass BeatFeed(Feed):\n    description_template = "feeds/beat_description.html"\n\n    def get_object(self, request, beat_id):\n        return Beat.objects.get(pk=beat_id)\n\n    def title(self, obj):\n        return "Police beat central: Crimes for beat %s" % obj.beat\n\n    def link(self, obj):\n        return obj.get_absolute_url()\n\n    def description(self, obj):\n        return "Crimes recently reported in police beat %s" % obj.beat\n\n    def items(self, obj):\n        return Crime.objects.filter(beat=obj).order_by("-crime_date")[:30]\n
\n

Chun ``, ``, agus <title>```` an bheatha <link>a ghiniúint, <description>úsáideann Django na modhanna `teideal () ``, link () agus ```cur síos (). Sa sampla roimhe seo, ba tréithe aicme teaghráin iad, ach léiríonn an sampla seo gur féidir leo a bheith ina mhodhanna teaghráin* nó*. I gcás gach ceann de teideal ``, `nasc agus tuairisc, leanann Django an algartam seo:

\n\n

Tabhair faoi deara freisin go leanann items () ``an algartam céanna freisin -- ar dtús, déanann sé iarracht ``items (obj), ansin items (), ansin ar deireadh tréith aicme ``earraí ``(ba chóir a bheith ina liosta).

\n

Táimid ag úsáid teimpléad do na tuairiscí earraí. Is féidir leis a bheith chomh íosta leis seo:

\n
Django template
{{ obj.description }}\n
\n

Mar sin féin, tá saor ort formáidiú a chur leis de réir mar is mian leat.

\n

Tugann an rang ExampleFeed thíos doiciméadú iomlán ar mhodhanna agus tréithe ranganna: Class: ~Django.Contrib.Syndication.Views.Feed.

An cineál beatha a shonrúLink to this heading#

\n

De réir réamhshocraithe, úsáideann fothaí a tháirgtear sa chreat seo RSS 2.0.

\n

Chun é sin a athrú, cuir tréith feed_type le d'aicme:class: ~django.contrib.syndication.views.feed, mar sin:

\n
Code
from django.utils.feedgenerator import Atom1Feed\n\n\nclass MyFeed(Feed):\n    feed_type = Atom1Feed\n
\n

Tabhair faoi deara go socraíonn tú feed_type le réad aicme, ní sampla.

\n

Is iad na cineálacha beatha atá ar fáil faoi láthair:

Chun imfhálacha a shonrú, amhail na cinn a úsáidtear chun fothaí podchraolta a chruthú, bain úsáid as an crúca item_enclosure nó, mura bhfuil ach imfhálú amháin agat in aghaidh an earra, na crúcaí item_enclosure_url ``, `item_enclosure_mime_type. Féach an rang ExampleFeed thíos le haghaidh samplaí úsáide.

TeangaLink to this heading#

\n

Feeds created by the syndication framework automatically include the\nappropriate <language> tag (RSS 2.0) or xml:lang attribute (Atom). By\ndefault, this is django.utils.translation.get_language(). You can change\nit by setting the language class attribute.

URLannaLink to this heading#

\n

Is féidir leis an modh/tréith nasc cosán iomlán a thabhairt ar ais (m.sh. ” /blog/") nó URL leis an bhfearann agus an prótacal láncháilithe (m.sh.``” https://www.example.com/blog/ “). <SITE_ID>Mura bhfilleann ``nasc an fearann ar ais, cuirfidh an creat siondicíochta fearann an láithreáin reatha isteach, de réir do shuíomh: `SET_ID `.

\n

Teastaíonn <link rel="self">```` i bhfothaí Atom a shainmhíníonn suíomh reatha an bheatha. Déanann an creat siondála é seo a líonadh go huathoibríoch, ag baint úsáide as fearann an láithreáin reatha de réir an shocraithe:setting: SITE_ID.

Fothaí Atom agus RSS a fhoilsiú in éineachtLink to this heading#

\n

Is maith le roinnt forbróirí leaganacha Atom* agus* RSS dá bhfothaí a chur ar fáil. Chun sin a dhéanamh, is féidir leat fo-aicme de do rang: ~django.contrib.syndication.views.feed a chruthú agus an feed_type` a shocrú go rud éigin difriúil. Ansin nuashonraigh do URLConf chun na leaganacha breise a chur leis.

\n

Seo sampla iomlán:

\n
Code
from django.contrib.syndication.views import Feed\nfrom policebeat.models import NewsItem\nfrom django.utils.feedgenerator import Atom1Feed\n\n\nclass RssSiteNewsFeed(Feed):\n    title = "Police beat site news"\n    link = "/sitenews/"\n    description = "Updates on changes and additions to police beat central."\n\n    def items(self):\n        return NewsItem.objects.order_by("-pub_date")[:5]\n\n\nclass AtomSiteNewsFeed(RssSiteNewsFeed):\n    feed_type = Atom1Feed\n    subtitle = RssSiteNewsFeed.description\n
\n\n

Agus an URLConf a ghabhann leis:

\n
Code
from django.urls import path\nfrom myproject.feeds import AtomSiteNewsFeed, RssSiteNewsFeed\n\nurlpatterns = [\n    # ...\n    path("sitenews/rss/", RssSiteNewsFeed()),\n    path("sitenews/atom/", AtomSiteNewsFeed()),\n    # ...\n]\n

Gineadóirí beatha saincheapthaLink to this heading#

\n

Más gá duit formáid beatha saincheaptha a tháirgeadh, tá cúpla rogha agat.

\n

Má tá an fhormáid beatha go hiomlán saincheaptha, beidh tú ag iarraidh “SyndicationFeed” a fho-aicmiú agus na modhanna write () ``agus `WriteString () a chur in ionad go hiomlán.

\n

Mar sin féin, más spin-off de RSS nó Atom é an fhormáid beatha (ie GeoRSS, formáid podchraoladh “iTunes” _ Apple, srl.), Tá rogha níos fearr agat. De ghnáth cuireann na cineálacha fothaí seo eilimintí agus/nó tréithe breise leis an bhformáid bhunúsach, agus tá sraith modhanna ann a ghlaonn SyndicationFeed chun na tréithe breise seo a fháil. Dá bhrí sin, is féidir leat an rang gineadóir beatha cuí a fho-aicmiú (Atom1Feed nó RSS201REV2Feed) agus na haisghlaonna seo a leathnú. Is iad seo a leanas:

\n
\n
``SyndicationFeed.root_attributs (féin) ``

Tabhair ar ais dict de thréithe le cur leis an eilimint beatha fréimhe (feed`/chainel).

\n
\n
``SyndicationFeed.Add_Root_Elements (féin, láimhseálaí) ``

Glaoigh ar ais chun eilimintí a chur leis taobh istigh den eilimint beatha fréimhe (feed``/channel ``). Is é ``handler an:class: ~xml.sax.saxutils.xmlGenerator ó leabharlann SAX ionsuite Python; glaoifidh tú modhanna air chun cur leis an doiciméad XML atá i bpróiseas.

\n
\n
``SyndicationFeed.Item_Attributes (féin, mír) ``

Tabhair ar ais dict de thréithe le cur le gach mír (ear/iontrála) eilimint. Is foclóir é an argóint, Item `, de na sonraí go léir a chuirtear chuig SyndicationFeed.add_item ()`.

\n
\n
``SyndicationFeed.Add_Item_Elements (féin, láimhseálaí, mír) ``

Glaoigh ar ais chun eilimintí a chur le gach eilimint (item/iontrála`). Tá ``handler agus ear mar atá thuas.

\n
\n
\n\n

Mar shampla, b'fhéidir go dtosóidh tú gineadóir beatha iTunes RSS a chur i bhfeidhm mar seo:

\n
Code
class iTunesFeed(Rss201rev2Feed):\n    def root_attributes(self):\n        attrs = super().root_attributes()\n        attrs["xmlns:itunes"] = "http://www.itunes.com/dtds/podcast-1.0.dtd"\n        return attrs\n\n    def add_root_elements(self, handler):\n        super().add_root_elements(handler)\n        handler.addQuickElement("itunes:explicit", "clean")\n
\n

Tá a lán níos mó oibre le déanamh le haghaidh rang beatha saincheaptha iomlán, ach ba cheart go léireodh an sampla thuas an bunsmaoineamh.

\n

Feed stylesheetsLink to this heading#

\n

If you wish to have your RSS feed render nicely in a browser, you will need to\nprovide styling information for the XML file, typically in XSLT or CSS\nformats.

\n

You can add this to your RSS feed by setting the stylesheets attribute on\nthe feed class.

\n

This can be a hardcoded URL:

\n
Code
from django.contrib.syndication.views import Feed\n\n\nclass FeedWithHardcodedStylesheet(Feed):\n    stylesheets = [\n        "https://example.com/rss_stylesheet.xslt",\n    ]\n
\n

You can also use Django's static files system:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.templatetags.static import static\n\n\nclass FeedWithStaticFileStylesheet(Feed):\n    stylesheets = [\n        static("rss_styles.xslt"),\n    ]\n
\n

Another option is to have a view in your project that renders the XSLT\ndocument. You can then link it like so:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.urls import reverse_lazy\n\n\nclass FeedWithStylesheetView(Feed):\n    stylesheets = [\n        reverse_lazy("your-custom-view-name"),\n    ]\n
\n

Django will normally try to guess the MIME type of the given URL based on its\nextension, but if that fails you can specify it using the\nStylesheet class:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.utils.feedgenerator import Stylesheet\n\n\nclass FeedWithHardcodedStylesheet(Feed):\n    stylesheets = [\n        Stylesheet("https://example.com/rss_stylesheet", mimetype="text/xsl"),\n    ]\n
\n

Similarly, if you'd like to use a different media attribute than screen\n(Django's default), you can use the\nStylesheet class again:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.utils.feedgenerator import Stylesheet\n\n\nclass FeedWithHardcodedStylesheet(Feed):\n    stylesheets = [\n        Stylesheet("https://example.com/rss_stylesheet.xslt", media="print"),\n    ]\n
\n

Any of these options can be combined when using multiple stylesheets:

\n
Code
from django.contrib.syndication.views import Feed\nfrom django.utils.feedgenerator import Stylesheet\n\n\nclass MultiStylesheetFeed(Feed):\n    stylesheets = [\n        "/stylesheet1.xsl",\n        Stylesheet("/stylesheet2.xsl"),\n    ]\n
\n
