Application error (500) TemplateLoadError: Loader cannot locate the template file "./X.html"l

[Yan Yi Fong]

Hello,

I'm trying to use an includable template and I get this error when trying to run it on Heroku. 
Application error (500) TemplateLoadError: Loader cannot locate the template file "./X.html"

The includable template works fine on otree devserver.

Includable template is in the same folder of the main html and this is what I wrote in the main html:
{% include "./X.html" %}

Does anyone have any idea? 

Thanks in advance.

Change it to {% include "my_app/X.html" %} rather than the dot.

Also check if the server is running the same version of otree.

Hello,

I have the same problem and I tried to follow the instructions from Chris but I don't know if I am doing well.

My App is called OrderQuantity Experiment and I have  10 Templates, when a I run my experiment in Heroku server, it run well only the templates from 1 to 5, and then not working and appear the error  TemplateLoadError: Loader cannot locate the template file ' OrderQuantity/treatment2.html'.

Just as  Yan Yi Fong my experiment work well in otree devserver.

I have some questions:

- I wrote before {% block title %} this line in each template {% include "OrderQuantity./treatment2.html" %} example for the page treatment2, it is correct? I guess no, because the error persist.

- I read you mention a main html, where is it? I have to write the code above into this main html.

Please help me, I tried to run the projects that I have imported from the otree course and all of them working in heroku except mine.

[Chris @ oTree]

On Heroku, names are case sensitive. is the template called treatment2.html or Treatment2.html?

[Hector Yomar Aguilar Lucas]

Hello Chris

Yeah, that was the problems. Into python script the name of the class is "treatment1", However the html file is called "Treatment1".

I have changed this, and now heroku is working.

Thanks you.
