Django ChoiceField
I'm trying to solve following issue:
I have a web page that can see only moderators.
Fields displayed on this page (after user have registered):
Username, First name+Last name, Email, Status, Relevance, etc.
I need to display table with information of all users stored in db with this fields, but two of fields have choices, so I want to make option that moderators can choose another option and after clicking on "Update" button this fields will be updated for selected user.
I can to display all choices of "status" and "relevance" fields, and after I choose new options from dropdown db is updated.
I want to display dropdowns and option stored in db should be selected.
I've tried a lot of options, I googled a lot of my time, and searched for answer or for right direction in StackOverFlow too, but didn't find anything.
Sorry for my bad english and thank you in advance for help!
Below is part of my code:
models.py:
class Profile(models.Model):
user = models.OneToOneField(User)
status = models.IntegerField(choices=((1, _("Not relevant")),
(2, _("Review")),
(3, _("Maybe relevant")),
(4, _("Relevant")),
(5, _("Leading candidate"))),
default=1)
relevance = models.IntegerField(choices=((1, _("Unread")),
(2, _("Read"))),
default=1)
forms.py:
class CViewerForm(forms.Form):
status = forms.ChoiceField(label="",
initial='',
widget=forms.Select(),
required=True)
relevance = forms.ChoiceField(widget=forms.Select(),
required=True)
views.py:
@group_required('Managers')
@render_to('reader/view.html')
def admins_view(request):
users_list = Profile.objects.select_related('user').all()
users_dict = dict()
if request.method and request.method == 'POST':
form = CViewerForm(request.POST)
if form.is_valid():
d = form.cleaned_data
# get all selected choices
status_list = request.POST.getlist('status')
relevance_list = request.POST.getlist('relevance')
# get all usernames viewed on page
users_list = request.POST.getlist('username')
# create dict from all those lists
users_dict = zip([user for user in users_list], [status for status in status_list], [rel for rel in relevance_list])
# run through dict and do bulk update
for user_dict in users_dict:
Profile.objects.filter(user__username=user_dict[0]).update(status=user_dict[1], relevance=user_dict[2])
return HttpResponseRedirect(reverse('reader:admins_view'))
else:
form = CViewerForm()
return {'users_list': users_list,
'user': request.user,
'form': form}
template:
<form class="form-horizontal" action="" method="post" name="update-form" class="well form-inline" id="view_form">
{% csrf_token %}
{{ form.non_field_errors }}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% if user.is_staff %}
<div>
<table class="table table-striped table-condensed">
<thead>
<tr>
<th>{% trans 'Username' %} </th>
<th>{% trans 'E-mail' %} </th>
<th>{% trans 'Status' %} </th>
<th>{% trans 'Relevance' %} </th>
</tr>
</thead>
<tbody>
{% for user in users_list %}
<tr>
<td><input type="text" READONLY name="username" value="{{ user.user.username }}"></td>
<td>{{ user.user.first_name }}</td>
<td>{{ user.user.last_name }}</td>
<td>{{ user.user.email }}</td>
<td>{{ user.get_status_display }}</td>
<td>{{ user.get_relevance_display }}</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
{% endif %}
<br>
{% endif %}
<div class="form-actions">
<input type="hidden" name="_cmd_personal">
<input type="submit" class="btn btn-info" value="{% trans 'Update' %}" name="update" class="default">
</div>
</form>
Below is a solution:
forms.py (as @Liarez wrote).
template:
<form class="form-horizontal" action="" method="post" name="update-form" class="well form-inline" id="view_form">
{% csrf_token %}
{% if user.is_staff %}
{% if users_list %}
<div>
<table class="table table-striped table-condensed">
<thead>
<tr>
<th>{% trans 'Username' %} </th>
<th>{% trans 'First name' %} </th>
<th>{% trans 'Last name' %} </th>
<th>{% trans 'E-mail' %} </th>
<th>{% trans 'CV Status' %} </th>
<th>{% trans 'CV Relevance' %} </th>
</tr>
</thead>
<tbody>
{% for user in users_list %}
<tr>
<td><input type="text" READONLY name="username" value="{{ user.user.username }}"></td>
<td>{{ user.user.first_name }}</td>
<td>{{ user.user.last_name }}</td>
<td>{{ user.user.email }}</td>
<td>
<select name="cv_status">
{% for key, status in status_choices %}
{% ifequal user.get_cv_status_display status %}
<option value="{{ user.cv_status }}" selected>{{ user.get_cv_status_display }}</option>
{% else %}
<option value="{{ key }}">{{ status }}</option>
{% endifequal %}
{% endfor %}
</select>
</td>
<td>
<select name="cv_signal">
{% for key, signal in signal_choices %}
{% ifequal user.get_cv_signal_display signal %}
<option value="{{ user.cv_signal }}" selected>{{ user.get_cv_signal_display }}</option>
{% else %}
<option value="{{ key }}">{{ signal }}</option>
{% endifequal %}
{% endfor %}
</select>
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
{% endif %}
<br>
{% endif %}
<div class="form-actions">
<input type="submit" class="btn btn-info" value="{% trans 'Update' %}" name="update" class="default">
</div>
First I recommend you as @ChrisHuang-Leaver suggested to define a new file with all the choices you need it there, like choices.py:
STATUS_CHOICES = (
(1, _("Not relevant")),
(2, _("Review")),
(3, _("Maybe relevant")),
(4, _("Relevant")),
(5, _("Leading candidate"))
)
RELEVANCE_CHOICES = (
(1, _("Unread")),
(2, _("Read"))
)
Now you need to import them on the models, so the code is easy to understand like this(models.py):
from myApp.choices import *
class Profile(models.Model):
user = models.OneToOneField(User)
status = models.IntegerField(choices=STATUS_CHOICES, default=1)
relevance = models.IntegerField(choices=RELEVANCE_CHOICES, default=1)
And you have to import the choices in the forms.py too:
forms.py:
from myApp.choices import *
class CViewerForm(forms.Form):
status = forms.ChoiceField(choices = STATUS_CHOICES, label="", initial='', widget=forms.Select(), required=True)
relevance = forms.ChoiceField(choices = RELEVANCE_CHOICES, required=True)
Anyway you have an issue with your template, because you're not using any {{form.field}}, you generate a table but there is no inputs only hidden_fields.
When the user is staff you should generate as many input fields as users you can manage. I think django form is not the best solution for your situation.
I think it will be better for you to use html form, so you can generate as many inputs using the boucle: {% for user in users_list %} and you generate input with an ID related to the user, and you can manage all of them in the view.
Better Way to Provide Choice inside a django Model :
from django.db import models
class Student(models.Model):
FRESHMAN = 'FR'
SOPHOMORE = 'SO'
JUNIOR = 'JR'
SENIOR = 'SR'
GRADUATE = 'GR'
YEAR_IN_SCHOOL_CHOICES = [
(FRESHMAN, 'Freshman'),
(SOPHOMORE, 'Sophomore'),
(JUNIOR, 'Junior'),
(SENIOR, 'Senior'),
(GRADUATE, 'Graduate'),
]
year_in_school = models.CharField(
max_length=2,
choices=YEAR_IN_SCHOOL_CHOICES,
default=FRESHMAN,
)
