Webservice update category, NTree is not regenerated

[eriknuds]

Hi,

 

I have the 1.6.0.14 version, and when I'm using the webservice call to update a category, the nleft and nright columns are left blank (even if they had no reason to change). Usually when you add/update a category using the GUI, the Category class will regenerate the NTree and repopulate the nleft/nright values. If this is not done, the category tree may disappear from the store pages.

The NTree regeneration is not done when updating a category using the webservice, and inspecting the Category class I see that doNotRegenerateNTree must have been set to true for this to happen. Yet I can find no place in the source code it is set to true, and I can see no way to set it to false so that after my update, the Category::regenerateEntireNtree() method is called. As PHP is not one of my native programming languages, I may have overlooked something though.

From the category class update() method:

 

if (!isset($this->doNotRegenerateNTree) || !$this->doNotRegenerateNTree)

{

Category::regenerateEntireNtree();

$this->recalculateLevelDepth($this->id);

}

 

Any ideas how the doNotRegenerateNTree is set to false, using the webservice, and how to prevent that, or how to force Category::regenerateEntireNtree(); to run in any way at all, using the webservice interface? I wouldn't mind having a way to turn regeneration off while I do a lot of category updates, then forcing it to happen at the end.

 

I see that the $webserviceParameters in the Category class adds the nleft and nright columns as hidden_fields but I'm not sure what to make of that and if this can be used to my advantage somehow.

 

I'd rather not override the class just to mend the webservice functionality, I hope there is a more generic solution - if it's a bug, it should just be fixed, though maybe it can be worked around for the time being as well.

I have the same problem with Prestashop 1.6.0.14. After changinging a category by the webservice, both the nleft and nrigth fields of the category are set to 0. It seems to be a bug in the webservice and should be fixed there! This bug is a blocker, because the related categories are displayed in the category tree furthermore, but clicking to them results in a 404 page!

 

prerequisites:

 

SELECT nleft,nright FROM `ps_category` WHERE `id_category`=12
--> nleft: 20; nright: 23

 

action:

 

PUT: http://localhost:8080/prestashop/api/categories/12

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<prestashop>
    <category>
        <id>12</id>
        <id_parent>3</id_parent>
        <active>1</active>
        <is_root_category>0</is_root_category>
        <name><language id="1">category name</language></name>
        <link_rewrite><language id="1">category_name</language></link_rewrite>
        <description><language id="1">category description</language></description>
        <date_add>2015-05-31 11:42:55</date_add>
    </category>
</prestashop>

 

current behavior after action:

 

--> nleft: 0; nright: 0

 

expected behavior after action:

 

--> nleft: 20; nright: 23

Hi,

 

I have same problem. I have same version 1.6.0.14

I also try to simulate a different <position> to force tree rebuilding, but sometime ignore also it.

 

Is there a solution or bug correction ?

 

Best regards,
