How get individual fields from django model?

Question

In my django models.py :

class Agent1(models.Model):
    show_name = models.CharField(db_column='Show_Name', max_length=100,null=True)
    exhibiting_company_name = models.CharField(db_column='Exhibiting_Company_Name', max_length=100,null=True) # Field name made lowercase.
    company_website = models.CharField(db_column='Company_Website', max_length=100,null=True)  # Field name made lowercase.
    company_generic_email = models.EmailField(db_column='Company_Generic_Email', max_length=100,null=True)  # Field name made lowercase.

class Agent2(models.Model):
    show_name = models.CharField(db_column='Show_Name', max_length=100,null=True)
    exhibiting_company_name = models.CharField(db_column='Exhibiting_Company_Name', max_length=100,null=True) # Field name made lowercase.
    company_website = models.CharField(db_column='Company_Website', max_length=100,null=True)  # Field name made lowercase.
    company_generic_email = models.EmailField(db_column='Company_Generic_Email', max_length=100,null=True)  # Field name made lowercase.

Like this i have around 30+ models this are just a few fields i have over 20 fields

& in my new_data.html file i have :

<form method="post"action="">{% csrf_token %}
{{ form.as_p}}
<input type="submit" name="" value="Submit">
</form>

How can i display only for eg show_name and exhibiting_company_name in my html template without creating a custom form in forms.py ?

Is there any way to call my model fields individually in a <input> tag like this :

<form action="demo_form.asp">
   Show Name: <input type="text" name="sname"><br/>
   Company Name: <input type="text" name="cname"><br/>
  <input type="submit" value="Submit">
</form> 

?

Answer 1

If you only want to display those fields, that's quite easy:

<form method="post" action="">
    {{ form.show_name }}<br/>
    {{ form.exhibiting_company_name }}<br/> 
    <input type="submit" value="Submit">
</form> 

But unless those are the only required fields, your form won't validate, and you won't know why since you're not displaying the error messages.

IOW, you will have to define a custom form. But really, using forms.ModelForm , it's only a couple lines of code.

Now for something totally different: having two or more models with the same schema and named "Model1", "Model2, (...), "ModelN" is a huge design smell. If they have the same schema, they are one single model (and one single table at the db level).

If I understood problem correctly you need to show only specific fields in template. For that you can iterate over all form's fields (see docs ) and display only those with specific names:

<form method="post" action="">
{% csrf_token %}
{% for field in form %}
    {% if field.name == "show_name" or field.name == "exhibiting_company_name" %}
        {{ field }}
    {% endif %}
{% endfor %}
<input type="submit" value="Submit">
</form>
