Do not render empty fields

[Barkalez XX]

Hello guys,

 I'm learning django and I have some doubts, I suppose that from now on you'll see me a lot here because my doubts are endless :).

I'm doing a simple recipe app, and some recipes have more ingredients than others and when I render them, empty fields take up space in the rendered HTML. I show you how the HTML is. I also include the repo in github.

Hi,

First of all I would say that I think you should rethink how you store the ingredients. What I would do is create a recipe model that has a number of ingredients (an ingredient model with a foreign key to the recipe). Therefor you would be able to do this in your template:

<h4>Ingredients</h4>

    <ul>

        {% for ingredient in receta.ingredients %}

             <li type="disc">{{ ingredient.name }}</li>

    </ul>

However - if you want to continue with your solution with a fixed number of ingredients you would be able to do this:

<h4>Ingredients</h4>

    <ul>

        <li type="disc">{{ receta.ingrediente_1 }}</li>

        {% if receta.ingrediente_2 %}<li type="disc">{{ receta.ingrediente_2 }}</li>{%endif%}

        {% if receta.ingrediente_3 %}<li type="disc">{{ receta.ingrediente_3 }}</li>{%endif%}

        {% if receta.ingrediente_4 %}<li type="disc">{{ receta.ingrediente_4 }}</li>{%endif%}

    </ul>

This code assumes that at least ONE ingredient should be present in each recipe. The others are added when needed.

Regards,

Andréas
