Related Fields not supported in Advanced Modules

patambrosio

Try this, create the sample categories_to_articles module in advanced modules, you will not be able to define a module for the related field ('categories' in the example), this might be because the framework is looking for the module in the main model folder and not your module's model folder.

I had to edit My_Model.php to get this working, I edited the function form_fields at line 1772 and line ~1778, and function initialize at line 115. This way, when defining related fields, I can write 'mymodule/categories' to tell the framework to load categories_model from your module's model directory. I'd share my code but it feels more like a quickfix than a solid solution.

Note: try fixing function form_fields first then testing before fixing function initialize, the $params variable in initialize is populated with a string, I don't know if this is correct behavior or a side-effect of my fix in line 1772 but I fixed it by adding another condition in line 115: is_array($params), hence I deem my solution a quickfix.

correction for first paragraph: ...you will not be able to define a module for the related field ('categories' in the example), and so your model will not load, this might be...

Would you mind posting the fix you have?

Can try changing lines 1764 to line 1781 in MY_Model to the following? For the key value use a slash syntax like so 'my_module/categories' :
if (!empty($related)) { $key_field = $this->key_field(); if (is_string($key_field)) { foreach($related as $key => $val) { // related need to be loaded usng $related_name = end(explode('/', $key)); $related_model = $this->load_model($key.'_model'); $lookup_model = $this->load_model($val); $options = $CI->$related_model->options_list(); $field_values = (!empty($values['id'])) ? array_keys($CI->$lookup_model->find_all_array_assoc($CI->$related_model->short_name(TRUE, TRUE).'_id', array($this->short_name(TRUE, TRUE).'_id' => $values[$key_field]))) : array(); $fields[$key] = array('label' => ucfirst($related_name), 'type' => 'array', 'class' => 'add_edit '.$key, 'options' => $options, 'value' => $field_values, 'mode' => 'multi'); } } }

Do I do this with a fresh copy of MY_Model, or over my altered copy?

admin

Fresh copy of MY_Model.

i have the same issue. I tried the fix suggested by admin but it still looks inside 'application' as far as i can see

admin

patambrosio, were you able go get this to work with the fix above or did you implement your own change?

patambrosio

I'm sorry for the unacceptable delay here, I was sidetracked by another project. I just got to test it now, I replaced my fix with yours and the initial problem I had returned.
