Here's the relavent HTML:
<form id="upload" method="POST" enctype="multipart/form-data"
action="/report/CDSEM/DR4iBeta/dr4iupload/">
<div style='display:none'><input type='hidden'
name='csrfmiddlewaretoken' value='XXXXXXXXXXX' /></div>
<div class="filter_group">
<div class="filter">
<label for="pixel_size">Pixel Size</label><br />
<input style="float: left; width: 40px" type="text"
disabled="True" value="6" id="pixel_size" name="pixel_size">
</div>
<div class="filter">
<label for="fov">FOV</label><br />
<input style="width: 30px" type="text" disabled="True"
value="3" id="fov" name="fov">
</div>
<div class="filter">
<label for="template_recipe">Template Recipe</label><br />
<input style="width: 200px" type="text" disabled="True"
value="SF/SF/SF/SF_Template_Recipe" id="template_recipe"
name="template_recipe">
</div>
<div class="filter">
<label for="template_target">Template Target</label><br />
<input style="width: 200px" type="text" disabled="True"
value="SF/SF/SF/SF_IMAQ_Template_Target" id="template_target"
name="template_target">
</div>
</div>
<div>
<input type="file" name="klarf_files" id="klarf_files" multiple=""
style="display: inline; padding-top: 5px; padding-left: 2px; " />
<input type="submit" class="submit" style="width: 70px; display:
inline;" value="Upload" />
</form>
The select the files with the file button and upload them with the
Upload botton. My view gets called, but I have the files in
request.FILES but I don't get the other 4 input fields.
Here's the relavent part of the view:
class UploadForm(forms.Form):
klarf_files = forms.FileField()
pixel_size = forms.CharField()
fov = forms.CharField()
template_recipe = forms.CharField()
template_target = forms.CharField()
def dr4iupload(self, request):
if request.method == 'POST':
form = UploadForm(request.POST, request.FILES)
if form.is_valid():
for file in request.FILES.getlist('klarf_files'):
.
.
.
I get the klarf_files, but I can't get the other 4 fields. The form
does not have the cleaned_data dictionary:
(Pdb) print form.cleaned_data()
*** AttributeError: 'UploadForm' object has no attribute 'cleaned_data'
