How to iterate through numbers in django

Question

I am new to Django. I just want to build an online resume based on the details given by the user. I have separate HTML files for taking the user input and for displaying the resume. I took the user input for the certification field like this:

<div class="box"><input type="text" name="certificate1" placeholder="Certificate-name"> <input type="text" name="institute1" placeholder="Institute-name"></div><br>
    <div class="box"><input type="text" name="certificate2" placeholder="Certicate-name">  <input type="text" name="institute2" placeholder="Institute-name"></div><br>
    <div class="box"><input type="text" name="certificate3" placeholder="Certicate-name">  <input type="text" name="institute3" placeholder="Institute-name"></div><br>
    <div class="box"><input type="text" name="certificate4" placeholder="Certicate-name">  <input type="text" name="institute4" placeholder="Institute-name"></div><br>
    <div class="box"><input type="text" name="certificate5" placeholder="Certificate-name">  <input type="text" name="institute5" placeholder="Institute-name"></div><br>
    <div class="box"><input type="text" name="certificate6" placeholder="Certicate-name">  <input type="text" name="institute6" placeholder="Institute-name"></div><br>

And the code which I have written in views.py file is this:

if(request.method=="POST"):
    dictionary = {str(i):request.POST[i].capitalize() for i in request.POST}
    return render(request,"form/resume.html",dictionary)

And the code which I have written for displaying certifications in the resume is this:

{% if certificate1 %}
    <li>{{certificate1}}, {{institute1}}</li>
    {% endif %}
    {% if certificate2 %}
    <li>{{certificate2}}, {{institute2}}</li>
    {% endif %}
    {% if certificate3 %}
    <li>{{certificate3}}, {{institute3}}</li>
    {% endif %}
    {% if certificate4 %}
    <li>{{certificate4}}, {{institute4}}</li>
    {% endif %}
    {% if certificate5 %}
    <li>{{certificate5}}, {{institute5}}</li>
    {% endif %}
    {% if certificate6 %}
    <li>{{certificate6}}, {{institute6}}</li>
    {% endif %}

But I feel the code that I have written in displaying certifications in resume [2nd code] is not efficient. Is there any other way of writing the 2nd code? I want to know, how can we use for loop if possible. Or is there any other way? Thanks in advance for your valuable answers.

You can group all your data in one array and pass them in your render function so you could iterate it in your Jinja template

I used many fields like skills, education, achievements, project details, and so on. And for each field, I have a maximum of 5 answers. So, I simply stored them in a dictionary by using a for loop in views.py file. Please check my edited question once. – Vallamkonda Neelima Aug 06 '20 at 16:05

Send certificates as a list to template like this:

certificates = [
    { "certificate": certificate1, "institute": institute1},
    { "certificate": certificate2, "institute": institute2}
]

Then in template, display it like this:

{% for c in certificates %}
    <li>{{c.certificate}}, {{c.institute}}</li>
{% endfor %}

@VallamkondaNeelima even then you can just use a list for iteration and add the dictionary inside it as a list element like this: `dictionary = [{str(i):request.POST[i].capitalize()} for i in request.POST]`. This will allow using loop in template as well. – Safiul Kabir Aug 06 '20 at 16:16

Try to use arrays so you can easily iterate through it. or if you just want to write in that way use string concatenation for the variable name like:

{% for x in '123456' %}
    {% with y=forloop.counter|stringformat:"s" %}
    {% with names="certificate"|add:y %}
        {% if names %}
          <li> {{name}} </li>
        {% endif %}
    {% endwith %}
    {% endwith %}
{% endfor %}

as I have seen that you have edited question... you are sending dict to template. So iterate through that using for loop.{% for key, values in certificates.items %}{{key}}{{value}}{% endfor %} – Peddi Sakila Aug 06 '20 at 16:19
But now the **certificate1** is not a variable, it is a string-- "certificate1" and the above code you have written displays certificate1 certificate2 certificate3 and so on but not the values of them which are provided in views.py – Vallamkonda Neelima Aug 06 '20 at 17:58
