Disable template caching for development in OpenCart 3

Question

I am making changes in my theme templates in OpenCart 3. Due to template caching I have to clear cache every time under "storage/cache" directory. It is very annoying when working and previewing changes frequently during development. Please provide some solution how we can configure caching according to production and development environment.

Note: I have already searched for solutions online but there is no solution related to template caching. Solutions are available to disable image caching but "Image Caching" and "Template Caching" are different features provided in Opencart.

No its not duplicate, Image caching is another thing and it is not panic during development. – Ribaudo

Absolutely right. @RajatJain – Cadaverine

What exact version do you have? I have 3.0.0.0 and I thought template caching was turned off. – Maffa

on opencart 3.0.2.0 version, you can disable caching – Peterec

Answer 1

You might need to upgrade to a more recent version of OpenCart3 - the first one (3.0.0.0) didn't have a way of doing this in the GUI.

More recent versions, such as 3.0.2.0, have a gear on the admin dashboard. Click the gear and you get options to disable caching.

Some times if changes has been made in controller and view files. Needs to removed from cache folder. Using ftp. As opencart latest version is using all cache outside of working directory – Twana

Answer 2

Another way to do this: Open to system\library\template\Twig\Cache\Filesystem.php, find following lines of code

public function load($key)
{
    if (file_exists($key)) {
        @include_once $key;
    }
}

Comment out as in the following code:

public function load($key)
{
    // if (file_exists($key)) {
    //      @include_once $key;
    // }
}

This will remove the template cache of the twig and recreate every time, once development is over you have to remove the comment.

This one works fine! Just don't forget to remove comments at the end! Thnx @rupak-nepali – Vanscoy

Just one problem. When I make changes directly in twig file, it didn't display in front'end but my code display in theme editor. And when I hit save from there, then it displays on front-end – Lupelupee

Answer 3

You can also do this from CODE directly if you have the access. Go to this file path below via ftp or cPanel:

system\library\template\Twig\Environment.php

Find

$this->debug = (bool) $options['debug'];

Replace:

$this->debug = (bool) true;

You need to make sure to include this step Randall has mentioned if you have use the editor. Or else all the other options. aka "developer settings cache off" won't matter. – Atrophied

Answer 5

I think you edit the template as the path: Design->Theme Editor before.

Clear all of the date in the oc_theme data table of your database.

Upvoted, this was my case, dont know why you get the down vote. – Hydrotaxis

Answer 6

Scott's answer is best but in case it's not available due to version or you want to disable it programmatically you can do this anywhere before the twig is rendered:

$this->config->set('template_cache', false);

Thank you. I didn't notice it. – Naraka

$this means the line must be inside a class or any of it's inheritance. which class it is supposed to be? or more specific, which file? – German

$this->config can be called from any controller, model and most library classes. The for controllers and models the magic method __get() is used to return $this->registry->get('config'). The op is asking about templating here so presumably they are making changes from within a controller somewhere. – Biysk

Answer 7

in OC 3.0.3.6, if you have some twig extension, like twig managers, after changes maded you should select that extention in modifications and refresh push button on top right corner.

P.S. loose whole day to find this, hope it helps someone

Answer 8

This is similar to Scott's answer but just on the database/backend. In case you can't rely on the UI and can only access the DB (like me, I'm messing up with the UI) it's on settings table search for 'developer_theme' key and set it to false or 0.

UPDATE `oc_setting` SET `value` = '0' WHERE `oc_setting`.`key` = 'developer_theme';
