Im trying to raise error for empty fields or fields which are not validating in form so Im doing this method below but I know this is not the best way...

views.py :

'KnowledgeForm': form,
'errors': str(form.errors),

but then in Django-template I have to use if for each field and im adding custom name for each field , i dont know why i cant use Verbose_name...

Template :

                    {% if errors %}
                    <div >
                        <p>
                            {% if KnowledgeForm.errors.KnowledgeTitle %}
                            عنوان دانش: {{ KnowledgeForm.errors.KnowledgeTitle }}
                            {% endif %}
            
                            {% if KnowledgeForm.errors.KnowledgeTextSummary %}
                             Summary: {{ KnowledgeForm.errors.KnowledgeTextSummary }}
                            {% endif %}
            
                            {% if KnowledgeForm.errors.KnowledgeFromDate %}
                            from Date: {{ KnowledgeForm.errors.KnowledgeFromDate }}
                            {% endif %}
            
                            {% if KnowledgeForm.errors.KnowledgetoDate %}
                           To date : {{ KnowledgeForm.errors.KnowledgetoDate }}
                            {% endif %}
            
                            {% if KnowledgeForm.errors.KnowledgeProcess %}
                            Chart: {{ KnowledgeForm.errors.KnowledgeProcess }}
                            {% endif %}
            
                          {% endif %}

                        </p>
                    </div>
                    {% endif %}

Second method :

                    {% if KnowledgeForm.errors %}
                        <ul >
                        {% for key,value in KnowledgeForm.errors.items %} 
                        <li>{{ key|escape }} : {{ value|escape }}</li>
                        {% endfor %}
                        </ul>
                    {% endif %}

in this method i get the name based on whats used in models.py how can i change it?

CodePudding user response：

The most clear and concise way is to use a forloop

Try replacing your entire if block in your HTML with the below code

{% for field in KnowledgeForm %}
    {% if field.errors %}
        <div >
             {{ field.label_tag }} {{ field.errors }}
        </div>
    {% endf %}
{% endfor %}

I don't think you need 'errors': str(form.errors),

CodePudding user response：

It is because you convert errors to str and you don't need to separate this.

In your template:

# if you want to use verbose_name just use label_tag.
# label_tag is equal to your verbose name.

{% for field in KnowledgeForm %}
    <div >
        {{ field.errors }}
        {{ field.label_tag }} {{ field }}
    </div>
{% endfor %}

So you have the error top of input
