I have a model for recipes. I have a model for reviews of those recipes. The recipe’s author (chef) can select a specific review as their favorite. I think I’ve set the constraint up correctly to only allow one favorite review per recipe. Let’s assume one favorite review per recipe.
I would like to reference the one favorite review using the recipe model. Is this possible? Example template snippet below.
<code>{% for recipe in recipes %}
<h2>{{ recipe.name }}</h2>
<p>{{ recipe.favoriteReview.content }} <small>by {{ recipe.favoriteReview.author }}</small></p>
<p>Email the chef: {{ recipe.chef.email }}</p>
<code>{% for recipe in recipes %}
<div>
<h2>{{ recipe.name }}</h2>
<p>{{ recipe.favoriteReview.content }} <small>by {{ recipe.favoriteReview.author }}</small></p>
<p>Email the chef: {{ recipe.chef.email }}</p>
</div>
{% endfor %}
</code>
{% for recipe in recipes %}
<div>
<h2>{{ recipe.name }}</h2>
<p>{{ recipe.favoriteReview.content }} <small>by {{ recipe.favoriteReview.author }}</small></p>
<p>Email the chef: {{ recipe.chef.email }}</p>
</div>
{% endfor %}
Here’s an example of the models but I feel like I’ve approached this from the wrong direction and I’ve hit a wall.
