Data base saving & Redirection issue using django - django

Question

I have an issue, I do not know why it is happening and how to solve it;
My app ask a user to create a project and is redirect directly to the project detail page. On that detail page if a team_id is empty I ask the user to create a team and when the team is created the user is redirected again to the project detail page to now be able to populate his team.
I used the code {% if Project.team_id == None %} when the user is redirected after creating his team but it is not working .. could you please help ? It is like before the redirection the new team is not saved in the Db ..
my html:
{% extends 'base.html' %}
{% block body %}
<div class="container">
<div class="jumbotron">
<h2>Welcome to your Project {{ project.name }} Detail page</h2>
</div>
{% if Project.team_id == None %}
<div class="invite-team">
<div class="jumbotron">
<div class="jumbo-text">
<h3>It is time to link a team to your project now create a new team and add team members</h3>
</div>
<div class="jumbo-button">
<span class="glyphicon glyphicon-plus"></span> Create a new team
</div>
</div>
{% else %}
<div class="invite-teammembers">
<div class="jumbotron">
<div class="jumbo-text">
<h3>The team {{ project.team_id }} has beed created, we now need to add TeamMembers</h3>
</div>
<div class="jumbo-button">
<span class="glyphicon glyphicon-plus"></span> Create a new team
</div>
</div>
</div>
{% endif %}
</div>
</div>
{% endblock%}

Looking at your surrounding code, you are using project as the container of your project. However, in your statement you are using Project (first character uppercase). Changing Project to project might help.
Your comment question:
what do you mean "Looking at your surrounding code, you are using project as the container of your project". my model Project is with a capital letter why now it is without ?
With looking at the surrounding code I mean that I literally looked at your code how you are using the variables in the other parts of your code. I am not sure if you are using CBV (class based views) or FBV (function based views).
With CBV the object is added to the context with the name defined in:
DetailView:81
or ListView:104
You can override the context object name by using the context_object_name in the View class
If you are using FBV, you have added it to the context manually as something like:
return render(request, 'myapp/template.html', {
'project': <project_query_or_variable>,
})
