python - Reading Checkbox in Django -
this not reading django checkbox. i've read through 7 different posts checkbox on here along 4 other pages in django documentation. situation bit different. can't read whether specific checkbox checked or not. value "true" both checkboxes when 1 checkbox checked. if nothing checked, worked expected. need use multiplechoicefield?
current output:
- john doe location true ===> checked - james smith location true ===> unchecked ideally, list of dictionary contains
data [0] = {'john', 'doe', 1} data [1] = {'john', 'smith', 0} ... where '1' flag overwrite , '0' ignore.
background:
- user submits form
- second form displays previous information checkbox next names if duplicates found. if they're not duplicate, no checkbox appear.
- read in checkbox, process, , display final page.
forms.py
from django import forms django.forms.formsets import baseformset class nameform (forms.form): first_name = forms.charfield (max_length = 20, required = false) last_name = forms.charfield (max_length = 20, required = false) class basenameformset (baseformset): ... class checkbox (forms.form): overwrite = forms.booleanfield (required = false) views.py
def addname (request): .... if request.method == 'post': .... if formset.is_valid (): location = request.post ['site'] data = formset.cleaned_data # store data session used in method request.session ['location'] = location request.session ['data'] = data def process (request): location = request.session ['location'] data = request.session ['data'] if request.method == 'post': form = checkbox (request.post) if form.is_valid (): overwrite = form.cleaned_data.get ('overwrite') # duplicate in checkboxes: # overwrite = duplicate.get ('overwrite') print (overwrite) context = {'data': data, 'location': location, 'overwrite': overwrite} return render (request, 'nodeform/success.html', context) return httpresponse ('no overwrite data.') response.html

all checkbox inputs have same attribute name=overwrite so, when check one, 1 submitted in post overwrite=true.
you should give unique name each input. suggest use {{ forloop.counter0 }}, provide current iteration of loop, starting 0. index of current "info" in "data".
{% info in data %} <tr> <td>{{ info.first_name }}</td> <td>{{ info.last_name }}</td> <td class="center"><input type="checkbox" name='overwrite-{{ forloop.counter0 }}'></td> ===> testing checkbox <!-- {% if info.overwrite %} <td class="center"><input type="checkbox" name='overwrite' value="1"></td> {% else %} <td class="center"></td> {% endif %} --> </tr> {% endfor %} this way, can match form field in post "info" in backend.
