Hello community
I am trying to build a simple form which can be opened using a button. It
should offer some fields which should be further process after validation.
And there is exactly my issue. When I write some data into the fields and
click the submit button. the validation error is NOT displayed below the
screen like in this screeshot:
[image: 2020-02-27_21-52-30.png]
but is displayed in the log.
Can somebody give me a hint what I am missing here?
Thanks a lot!!
Sunil
This is the code I am using:
my HTML Code for presenting the form.
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{%block content%}
<br>
<h1 style="color:black">Add System to Organization</h1>
<br>
<div class="col" style="color:black">
<form method="post" action="{% url 'chr_add_system' %}" class="uniForm">
{% csrf_token %}
{{form|crispy}}
<input type="submit" value="Submit"/>
</form>
</div>
<br>
{%endblock content%}
the view:
def chr_add_system_view(request):
if request.method == 'POST':
form = AddChrSystemForm(request.POST)
if form.is_valid():
print('add_system-------->valid')
# TODO: do something
return redirect(chr_systems_view)
else:
print('form.errors ' + str(form.errors))
form = AddChrSystemForm()
context = {'form': form}
return render(request=request, template_name='chr/add_system.html',
context=context)
the form:
class AddSystemForm(ModelForm):
def __init__(self, *args, **kwargs):
super(AddSystemForm, self).__init__(*args, **kwargs)
self.fields['profile_name'].widget.attrs['readonly'] = True
class Meta:
model = System
fields = '__all__'
def clean_system_id(self):
print('validating oid of system..')
system_id = self.cleaned_data['system_id']
print('system_id: ' + system_id)
if "2.16" not in system_id:
print('oid of system id is invalid')
raise forms.ValidationError(
"Your submissionset source oid seems to be invalid. ==> it has
to be a valid oid and must start with: 2.16")
print('oid of system id is valid')
return system_id
the button where the form is called:
<div class="col system_title">
<font style="color:Black;"><b>SourceId</b></font>
<form method="post" action="{% url 'add_system' %}" class="uniForm">
{% csrf_token %}
<button type='submit' name="add_system"
class="btn btn-warning btn-sm float-right"
value="{{item0}}">[WIP] Add System
</button>
</form>
</div>
my class
class System(models.Model):
system_id = models.CharField(max_length=100)
abbreviation = models.CharField(max_length=100, default="SRC-")
software_name = models.CharField(max_length=100, default="Portal")
vendor = models.CharField(max_length=100, default="vendor")
profile_name = models.CharField(max_length=100, default="Source")
