FormModel not validating the fields

[faizan...@gslab.com]

I have created a form using form Model and added the def_clean method but the clean method is not being called . Here are my files 

models.py

class EmployeeData(models.Model):
 Yes = "Yes"
 No = "No"
 Onboard='Onboard'
 Left='Left'
 Is_GUEST_CHOICES = (
 (Yes, 'Yes'),
 (No, 'No'),
 )

 STATUS_CHOICES = (
 (Onboard, 'Onboard'),
 (Left, 'Left'),
 )
 gslab_id = models.CharField(max_length=20)
 name = models.CharField(max_length=100)
 email = models.CharField(max_length=100)
 is_guest = models.CharField(max_length=50,choices=Is_GUEST_CHOICES,default=No)
 status = models.CharField(max_length=50,choices=STATUS_CHOICES,default=Onboard)
 password = models.CharField(max_length=100,null=True)
 updated_at = models.DateTimeField(auto_now_add=True)
 created_at = models.DateTimeField(auto_now_add=True)

Forms.py 


from django import forms
from .models import EmployeeData
from django.core.exceptions import ValidationError


class LoginForm(forms.ModelForm):
 class Meta:
 model = EmployeeData
 fields = ('gslab_id', 'password',)
 gslab_id= forms.CharField(widget=forms.TextInput(attrs = {'class':'form-control white-text'}))
 password= forms.CharField(widget=forms.PasswordInput(attrs = {'class': 'form-control white-text'}))

def clean_gslab_id(self, *args, **kwargs):
 user_id = self.cleaned_data.get('gslab_id')
 if not "cfe" in user_id:
 raise forms.ValidationError('This is not valid title')
 return user_id

views.py

def getLogindata(request):
 if request.method == 'POST':
 login_form = LoginForm(request.POST or None)
 # return HttpResponse(login_form['gslab_id'])

 if login_form.is_valid():
 emp_model=EmployeeData()
 emp_model.gslab_id=login_form['gslab_id']
 emp_model.password=login_form['password']

 emp_model.save()
 return redirect("/home")


 else:
 context={
 'login_form':login_form
 }
 return render(request, 'login.html', context)

template

<form name="loginForm" method="post" action="/processLogin/">
 {% csrf_token %}
 {# Heading #}
 <h3 class="white-text text-center">
 <strong>Login</strong>
 </h3>
 {% if login_form.errors %}
 {% for field in form %}
 {% for error in field.errors %}

 <p>{{ error}}</p>

 {% endfor %}
 {% endfor %}
 {% endif %}
 <hr>
 <div class="md-form">
 <i class="fa fa-user prefix white-text"></i>
 {% if login_form %}
 {{ login_form.gslab_id }}
 {% endif %}
 <label for="username" class="white-text">Employee Id</label>
 </div>
 <div class="md-form">
 <i class="fa fa-lock prefix white-text"></i>
 {% if login_form %}
 {{ login_form.password }}
 {% endif %}
 <label for="password" class="white-text">Password</label>
 </div>
 <div class="text-center">
 <button type="submit" class="btn btn-indigo custom-button">Login</button>
 </div>
</form>

It’s difficult to tell with your spacing in the email.  The function needs to be inside the class, not outside.

Hi,

Your code is a bit hard to read. Python is whitespace significant and you should have more than one space for indentation of methods in classes and so on.

From what I can see it doesn't look like the clean method is a method in the LoginForm class?

Check here for the official docs:

https://docs.djangoproject.com/en/2.1/ref/forms/validation/#cleaning-a-specific-field-attribute

Also, there is no need for the *args and **kwargs on the method, because those will not be used.

Regards,

Andréas
