Urlencode vs. iriencode
What's the difference between the template filters urlencode and iriencode? When should I use one over the other (or use both)? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Urlencode vs. iriencode
Anyone? I haven't found anything that describes the difference (except that one is for URI's and the other for URLs).

Re: Urlencode vs. iriencode
Here's the code for the two (the numbers at the start of each line are
just line numbers from the file) -
iriencode:
128 """
129 Convert an Internationalized Resource Identifier (IRI) portion to a URI
130 portion that is suitable for inclusion in a URL.
131
132 This is the algorithm from section 3.1 of RFC 3987. However,
since we are
133 assuming input is either UTF-8 or unicode already, we can
simplify things a
134 little from the full method.
135
136 Returns an ASCII string containing the encoded result.
137 """
138 # The list of safe characters here is constructed from the
"reserved" and
139 # "unreserved" characters specified in sections 2.2 and 2.3 of
RFC 3986:
140 # reserved= gen-delims / sub-delims
141 # gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@"
142 # sub-delims = "!" / "$" / "&" / "'" / "(" / ")"
143 # / "*" / "+" / "," / ";" / "="
144 # unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
145 # Of the unreserved characters, urllib.quote already considers all but
146 # the ~ safe.
147 # The % character is also added to the list of safe characters
here, as the
148 # end of section 3.1 of RFC 3987 specifically mentions that %
must not be
149 # converted.
150 if iri is None:
151 return iri
152 return urllib.quote(smart_str(iri), safe="/#%[]=:;$&()+,!?*@'~")
urlencode:
11 """
12 A version of Python's urllib.quote() function that can operate
on unicode
13 strings. The url is first UTF-8 encoded before quoting. The
returned string
14 can safely be used as part of an argument to a subsequent
iri_to_uri() call
15 without double-quoting occurring.
16 """
17 return force_unicode(urllib.quote(smart_str(url), safe='/'))
So iriencode only encodes the IRI portion (hence the longer list of
safe characters), while URL will encode the entire URL, including any
GET arguments and anchors.
As for usage, I haven't encountered any IRIs, but I believe IRIs need
to be encoded before inclusion in HTML (i.e. you can't just include
the non-ASCII characters in HTML). As for urlencode, its main purpose
is if you're including a URL in a form submission, e.g. the URL to go
to after login. urlencode will do everything that iriencode does, but
sometimes you might not want it to do that.

Re: Urlencode vs. iriencode
Awesome, thank you. So as far as escaping user-entered data for use
in URLs...urlencode is best?

I'd say so. I haven't really found a need for iriencode personally,
and from the code, it seems that urlencode does everything iriencode
does anyway.
