I can't get my django app to post to the db. I'm trying to pass my foreign key so I can post it correctly.
Sorry if it's something basic I'm missing I'm just starting. I think it never gets to form = ResultForm(request.POST). And just gives me the form = ResultForm.
Here is my code:
Model:
class Result(models.Model):
category = models.ForeignKey(Category)
category_result = models.CharField(max_length=200)
rating = models.DecimalField('', '', 8, 3)
votes = models.IntegerField(default=0)
created_by = models.IntegerField(default=0, null=True, blank=True)
created_on = models.DateTimeField('created on')
def __unicode__(self):
return self.category_result
Form:
class ResultForm(forms.ModelForm):
category_result = forms.CharField(max_length=200,help_text="Your best line")
rating = forms.DecimalField(widget=forms.HiddenInput(), initial=0)
votes = forms.IntegerField(widget=forms.HiddenInput(), initial=0)
created_by = forms.IntegerField(widget=forms.HiddenInput(), initial=1)
category = forms.IntegerField(widget=forms.HiddenInput())
class Meta:
model = Result
fields = ('category_result', 'rating', 'votes')
view:
def help_out(request, category_id):
if request.method == 'POST':
form = ResultForm(request.POST)
if form.is_valid():
form.save(commit=False)
form.category = category_id
form.save()
return index(request)
else:
print form.errors
else:
form = ResultForm
context = {'form': form, 'category_id': category_id}
return render(request,'pocketwingman/help_out.html', context)
template:
<!DOCTYPE html>
<html>
<head>
<title>Pocketwingman</title>
</head>
<body>
<h1>Add a Result</h1>
<form id="result_form" method="post" action="/pocketwingman/help_out/{{category_id}}/">
{% csrf_token %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in form.visible_fields %}
{{ field.errors }}
{{ field.help_text}}
{{ field }}
{% endfor %}
<input type="submit" name="submit" value="Create Line" />
</form>
</body>
</html>
url config:
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^(?P<category_id>\d+)/$', views.help_me, name='help_me'),
url(r'^help_out/(?P<category_id>\d+)/$', views.help_out, name='help_out'),
)
You should initiate your form if it's not a POST:
else:
form = ResultForm()
append () to form class.

Faced with such a problem, the exercise_new page does not display any form and does not display information from the DB.

You need to have:
{% if request.user.is_active %}
Instead of
{% if user.is_active %}
In your template.
I am trying to add a comment section to add a comment section to my blog detail using django but when i run my server i get no error in the development server and the comments are not being displayed. I added the comments from my admin site.
The snippet of my code is below.

in your template you use

you should use {% for comment in detail.comments.all %}
I have a Candidat models and Experience_Pro models as shown below with fk relation between them .
i can register or login a candidat(user) and a profil page with firstname and lastname of that candidat shown, and a form for Experience_Pro for the user to add if he does have one .
but when i enter all the info in the Experience_Pro form and click update nothing is added to candidat
I don't know what i am missing but the form is showing with no errors and even after i update the profile no errors but nothing is saved to candidat
models.py
class Candidat(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)

You need to do some update:
#login_required
def profil(request):
if request.method == 'POST':
exp_form = CreateExperience_Pro(request.POST)
c_form = UpdateCandidat(request.POST)
if exp_form.is_valid() and c_form.is_valid():
exp = exp_form.save()
candidat = c_form.save()
return redirect('profil')
else:
context = {

}
return render(request, 'candidats/profil.html', context)
else:
exp_form = CreateExperience_Pro()
c_form = UpdateCandidat()
context = {'exp_form': exp_form, 'c_form': c_form}
return render(request, 'candidats/profil.html', context)
I'm trying to get a list of objects in Django from a model.
I just want to get the list of 'dht node' from the request user, but it shows nothing in the html file (as if the list was empty). The user that I'm using has 2 'dht nodes' and they're shown in the django admin.
I don't know what is wrong, because if I use the instruction "member.dht.create(...)" in the views function and a create a new 'dht node' like this, this is shown. Only 'dht nodes' that I enter by form do not show. Can be the form?
Thanks a lot, Here's my code:
Models.py
class Node(models.Model):
name = models.CharField(primary_key=True, null=False, max_length= 50)
description= models.CharField(default=None, null=False, max_length= 250)
topic=models.CharField(default=None, null=False, max_length= 50, unique=True)
def __unicode__(self):
return self.name
class dht(Node):
temp = models.IntegerField(default=None, null=True)
hum = models.IntegerField(default=None, null=True)
class UserProfile(User):
uid = models.CharField(default=None, null=False, max_length= 250)
dht = models.ManyToManyField(dht, blank=True)
def __unicode__(self):
return self.user.username
Views.py -dht list-
#login_required(login_url = '/web/login')
def listDhtSensor(request):
member = request.user.userprofile
list = member.dht.all()
return render(request, 'web/listDhtSensor.html', {'list':list})
Html -listDhtSensor.html-
{% block content %}
{% for dht in list %}
{{ dht.name }}
{{ dht.topic }}
{% endfor %}
{% endblock %}
Forms.py
class newDHTSensorForm(forms.ModelForm):
class Meta:
model = dht
field = ['name',
'description',
'topic',]
labels = {'name': 'Name' ,
'description': 'Description',
'topic': 'Topic',}
exclude = ['temp', 'hum']
Views.py -dht form-
#login_required(login_url = '/web/login')
def newDHTSensor(request):
if request.method == "POST":
form = newDHTSensorForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.save()
return redirect('/web/dhtDetail')
else:
form = newDHTSensorForm()
return render(request, 'web/newDhtSensor.html', {'form': form})
Html -newDhtSensor.html-
{% block content %}
<div class="boxReg">

It shows nothing because you did not link you dht objects to that UserProfile, so if you later query for the dhts for that UserProfile, evidently the list is empty. You should add it to the dht relation, like:
#login_required(login_url = '/web/login')
def newDHTSensor(request):
if request.method == "POST":
form = newDHTSensorForm(request.POST)
if form.is_valid():
post = form.save()
request.user.userprofile.dht.add(post)
return redirect('/web/dhtDetail')
else:
form = newDHTSensorForm()
return render(request, 'web/newDhtSensor.html', {'form': form})
Note that you first need to save the post, so you should omit the commit=False aprameter.
The Django project that I am working on lists patient details and lets the user edit the details. I have been able to list it out but views.py is not getting linked to the url for updating the list.
views.py:
def update_patient(request, patient_id):
patient = Patient.objects.get(id=patient_id)
if request.method != 'POST':
form = PatientForm(instance=patient)
else:
# POST data submitted; process data.
form = PatientForm(instance=patient, data=request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse('patient:patient',
args=[patient.id]))
context = { 'patient': patient, 'form': form}
return render(request, 'patient/update_patient.html', context)
models.py:
class Patient(models.Model):
patientID = models.CharField(max_length=20)
firstName =models.CharField(max_length=20)
lastName = models.CharField(max_length=20)
age = models.IntegerField(max_length=None)
SSN = models.CharField(max_length=15)
address = models.CharField(max_length=200)
date_added = models.DateTimeField(auto_now_add=True)
urls.py:
url(r'^patients/(?P<patient_id>\update\d+)/$', views.update_patient, name='update'),
update_patient.html:
{% extends "patient/base.html" %} {% block content %}
<p>{{ patient }}
</p>
<p>Update Patient:</p>
<form action="{% url 'patient:update' patient.id %}" method='post'>
{% csrf_token %} {{ form.as_p }}
<button name='submit'>add entry</button>
</form>
{% endblock content %}
Your URL pattern is wrong, you have \update within capturing group, it shouldn't be, change the pattern to this:
url(r'^patients/(?P<patient_id>\d+)/update/$', views.update_patient, name='update')
