Re: Image input missing from POST request

Abhishek,

Good tip about the <input form="..."> syntax!  I didn't realize
you could do that to avoid having to nest the <input> fields
inside the <form>.


I just looked it up at:
- http://www.w3schools.com/tags/att_input_form.asp
where it says 2 interesting things:
- Not supported in IE
- Can specify multiple forms that the same input field is
   a part of, so presumably, the field would be POSTed with
   any of the listed forms.  Rest of the page does not make
   it obvious how to do that though.  Value is a string of
   space-separated form ids perhaps?

Any comment of either of these 2?  Have you tried your app
on IE?  Have you tried specifying multiple forms?

Thanks!

Hi Collin,

Thanks for taking time out to look at this. It turns out that Isomehow I copied the rendered HTML wrong! The real problem was thatthe form id used in input was incorrect and this was the reason forthe file not getting uploaded.

Separately, this is not really a trick but a fairly standard techniquenowadays, and after correcting my mistake, it works just fine.


Thanks,
Abhishek

    Hi,

    I certainly am learning something new about <input
    form="id_of_form">. However, it may be that that trick simply
    doesn't work correctly for file fields. My question is: _does_ it
    work correctly when the <input> is a child of the <form>?

        Hey Donarb,

        Input fields are not required to be inside form elements, so
        long as they specify the form attribute as I have done. Check
        the form attribute here
        
<https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input#Attributes>
        for reference.
        Moreover, I have other input fields as well which are outside
        the form element, but they get successfully submitted.

        Any other suggestions anyone?

        Thanks,
        Abhishek

                Hi,

                This is probably not a Django issue, but just trying
                my luck.

                I have an |input| field corresponding to a Django
                |ImageField| in a Django template. Rendered, the HTML
                looks like:

|<form action="/accounts/username/"method="post"id="profile_form"

                       enctype="multipart/form-data">
                </form>
                ... (other input fields and elements)
                <input  form="profile_form"  id="id_profile_pic"  name="profile_pic"  
type="file"  />|

                The corresponding |View| is an |UpdateView|. I found
                |request.FILES| to be empty and
                |request.cleaned_data| to contain |'profile_pic': None|.

                I used firebug to track the POST data. It contained
                other fields but not |profile_pic|.

                Can anyone say why the file does not get uploaded?
                I've posted this question to StakOverflow
                
<http://stackoverflow.com/questions/27059357/image-input-missing-from-post-request>
 as
                well, in case someone wants reputation points.

                Thanks,

            The input field is outside the closing </form> tag so
            would not be uploaded as part of the form.
