Django return xml template
A simple renderer that simply returns pre-rendered HTML. Unlike other renderers, the data passed to the response object should be a string representing the content to be returned.
This renderer will determine which other renderer would have been given highest priority, and use that to display an API style response within the HTML page. By default the response content will be rendered with the highest priority renderer apart from BrowsableAPIRenderer. Note that views that have nested or list serializers for their input won't work well with the AdminRenderer , as the HTML forms are unable to properly support them. For HyperlinkedModelSerializer this will be the case, but for ModelSerializer or plain Serializer classes you'll need to make sure to include the field explicitly.
Renders data returned by a serializer into an HTML form. This renderer is used for rendering HTML multipart form data. It is not suitable as a response renderer , but is instead used for creating test requests, using REST framework's test client and test request factory.
To implement a custom renderer, you should override BaseRenderer , set the. If provided, this is the accepted media type, as determined by the content negotiation stage. By default this will include the following keys: view , request , response , args , kwargs. The following is an example plaintext renderer that will return a response with the data parameter as the content of the response.
By default renderer classes are assumed to be using the UTF-8 encoding. To use a different encoding, set the charset attribute on the renderer. Note that if a renderer class returns a unicode string, then the response content will be coerced into a bytestring by the Response class, with the charset attribute set on the renderer used to determine the encoding. If the renderer returns a bytestring representing raw binary content, you should set a charset value of None , which will ensure the Content-Type header of the response will not have a charset value set.
Doing so will also ensure that the browsable API will not attempt to display the binary content as a string. In some cases you might want your view to use different serialization styles depending on the accepted media type. If you need to do this you can access request.
In some cases you might want a renderer to serve a range of media types. Typically a renderer will behave the same regardless of if it's dealing with a regular response, or with a response caused by an exception being raised, such as an Http or PermissionDenied exception, or a subclass of APIException.
To create any syndication feed, all you have to do is write a short Python class. You can create as many feeds as you want. Use this extra argument to pass the syndication framework the feeds that should be published under that URL. A Feed class is a simple Python class that represents a syndication feed. A feed can be simple e. Feed classes must subclass django. They can live anywhere in your code tree.
We need to tell the framework what data to put into those elements. Note that the. For the previous LatestEntries example, we could have very simple feed templates.
The slug here is "tags". The syndication framework sees the extra URL bits after the slug — 'python' and 'cats' — and gives you a hook to tell it what those URL bits mean and how they should influence which items get published in the feed. In this case, bits is ['python']. ObjectDoesNotExist if given invalid parameters. That function raises Tag.
DoesNotExist on failure, and Tag. In the previous example, they were simple string class attributes, but this example illustrates that they can be either strings or methods. For each of title , link , and description , Django follows this algorithm:. Finally, note that items in this example also takes the obj argument. The algorithm for items is the same as described in the previous step — first, it tries items obj , then items , and then finally an items class attribute which should be a list.
By default, the syndication framework produces RSS 2. Currently available feed types are shown in Table To specify enclosures i.
The syndication framework populates this automatically. Some developers like to make available both Atom and RSS versions of their feeds. Then update your URLconf to add the extra versions.
This information helps search engines index your site. The Django sitemap framework automates the creation of this XML file by letting you express this information in Python code. To create a sitemap, you just need to write a Sitemap class and point to it in your URLconf. Note that the dot character in sitemap.
The name of the sitemap file is not important, but the location is. Search engines will only index links in your sitemap for the current URL level and below.
For instance, if sitemap. It may also map to an instance of a Sitemap class e. In contrast to HttpRequest objects, which are created automatically by Django, HttpResponse objects are your responsibility. Each view you write is responsible for instantiating, populating, and returning an HttpResponse.
The HttpResponse class lives in the django. Typical usage is to pass the contents of the page, as a string, bytestring, or memoryview , to the HttpResponse constructor:.
But if you want to add content incrementally, you can use response as a file-like object:. Finally, you can pass HttpResponse an iterator rather than strings. HttpResponse will consume the iterator immediately, store its content as a string, and discard it.
Objects with a close method such as files and generators are immediately closed. If you need the response to be streamed from the iterator to the client, you must use the StreamingHttpResponse class instead. To set or remove a header field in your response, use HttpResponse. This proxies to HttpResponse. HTTP header fields cannot contain newlines. The HttpResponse. To tell the browser to treat the response as a file attachment, set the Content-Type and Content-Disposition headers.
For example, this is how you might return a Microsoft Excel spreadsheet:. A case insensitive, dict-like object that provides an interface to all HTTP headers on the response. See Setting header fields.
A string denoting the charset in which the response will be encoded. The HTTP status code for the response. The HTTP reason phrase for the response. This attribute exists so middleware can treat streaming responses differently from regular responses. True if the response has been closed. Instantiates an HttpResponse object with the given page content, content type, and headers. Other types will be converted to a bytestring by encoding their string representation. Iterators should return strings or bytestrings and those will be joined together to form the content of the response.
If not provided, a default phrase will be used. The headers parameter was added. Sets the given header name to the given value. Both header and value should be strings. Deletes the header with the given name. Returns True or False based on a case-insensitive check for a header with the given name. Acts like dict. Sets a cookie. The parameters are the same as in the Morsel cookie object in the Python standard library.
If expires is not specified, it will be calculated. Use domain if you want to set a cross-domain cookie. Otherwise, a cookie will only be readable by the domain that set it. RFC states that user agents should support cookies of at least bytes. For many browsers this is also the maximum size.
Use in conjunction with HttpRequest. You can use the optional salt argument for added key strength, but you will need to remember to pass it to the corresponding HttpRequest. This method makes an HttpResponse instance a file-like object. Returns the value of HttpResponse. This method makes an HttpResponse instance a stream-like object. Always False. Always True. Writes a list of lines to the response. Line separators are not added.
Like HttpResponse , these subclasses live in django. The first argument to the constructor is required — the path to redirect to. This can be a fully qualified URL e. In that last case, the client browser will reconstruct the full URL itself according to the current path. See HttpResponse for other optional constructor arguments. Note that this returns an HTTP status code This read-only attribute represents the URL the response will redirect to equivalent to the Location response header.
Acts just like HttpResponse but uses a status code. Like HttpResponse , but uses a status code. The first argument to the constructor is required: a list of permitted methods e.
If a custom subclass of HttpResponse implements a render method, Django will treat it as emulating a SimpleTemplateResponse , and the render method must itself return a valid response object.
