Revisions and Translation Issue - double json encode

[Spodnet]

I've been testing the revisions code with translations, and it appears to double encode and add the content as a language when a revision is made.

Change 1 From:
{"en":"Test"}

Change 1 To:
{"en":"Changed Test"}

Then undo the change:

Change 2 From:
{"en":"Changed Test"}

Change 2 To:
{"en":"{\"en\":\"Test\"}"}

This appears to happen when update() is called, the translation trait checks the field is translatable and adds the locale on. I thought possibly saving direct:

$entry->{$revision->key} = $revision->old_value; $entry->save();

would work but it doesn't seem to save correctly either

Hi @Spodnet , thank you for reporting this. It seems to be the same issue as #20 so let's move the conversation there. Cheers!

Hello. Sorry for my bad english.

Is this problem still not resolved?

On any return of the revision, there is a wrapper in the default localization

It looks like this
{"ru": "{" ru \ ": " {\\ "ru \": \\ "\\ u041e \\ u0442 \\ u0447 \\ u0451 \\ u0442 Voluptas quidem assumenda et non beatae. \\ "} "} "}

This is three times the return of the field revision

It looks like the HasTranslations component

when creating any entry in $ translatable fields

Creates a json "en" wrapper

Please help me to figure out at what stage the localization key is substituted.

Hello @ASVVIZIT this issue is from 2017.

Not sure what was it though. What version are you using ? Run:

php artisan backpack:version

Also when you change languages in configs clear config cache ``php artisan config:clear`.

If in the later versions 4.1 of backpack, please open a new issue, and provide steps to reproduce it.

Thanks,
Pedro

dear @tabacitu , i changed restoreRevision function in ReviseOperation.

revise-operation/src/ReviseOperation.php

Line 109 in eb04010

public function restoreRevision($id)

new code is :

public function restoreRevision($id)
    {
        $this->crud->hasAccessOrFail('revise');

        $revisionId = \Request::input('revision_id', false);
        if (! $revisionId) {
            abort(500, 'Can\'t restore revision without revision_id');
        } else {
            $entry = $this->crud->getEntryWithoutFakes($id);
            $revision = Revision::findOrFail($revisionId);

            // save current entry and revision temporary
            $this->data['entry'] = $entry;
            $this->data['revision'] = $revision; 

            // check if revision key is translatable in $entry model
            if( $this->isTranslatable($revision->key) ) {
            	$this->prepareTranslationsForRevision();

                $this->forgetLocalesThatAreNotExistInRevision();

                $this->returnForgettenLocalesThatAreNotExistInCurrentVersion();

                $this->updateAllLocalesThatAreCommonInOldAndCurrentVersion();
                
                $entry->update();
            } 
            else {
                // Update the revisioned field with the old value
                $entry->update([$revision->key => $revision->old_value]);
            }

            $this->data['entry'] = $this->crud->getEntry($id);
            $this->data['crud'] = $this->crud;
            $this->data['revisions'] = $this->crud->getRevisionsForEntry($id); // Reload revisions as they have changed

            // Rebuild the revision timeline HTML and return it to the AJAX call
            return view($this->crud->get('revise.timelineView') ?? 'revise-operation::revision_timeline', $this->data);
        }
    }

    private function isTranslatable($key)
    {
        return method_exists($this->data['entry'], 'isTranslatableAttribute') && 
            	$this->data['entry']->isTranslatableAttribute($key);
    }

    private function prepareTranslationsForRevision()
    {
        $this->data['old_values'] = $this->data['entry']->fromJson($this->data['revision']->old_value, false);
        $this->data['current_values_locales'] = collect($this->data['entry']->getTranslatedLocales($this->data['revision']->key));
        $this->data['old_values_locales'] = collect(array_keys($this->data['old_values']));   
    }

    private function forgetLocalesThatAreNotExistInRevision()
    {
        foreach ($this->data['current_values_locales']->diff($this->data['old_values_locales']) as $locale) {
            $this->data['entry']->forgetTranslation($this->data['revision']->key, $locale);
        }
    }

    private function returnForgettenLocalesThatAreNotExistInCurrentVersion()
    {
        foreach ($this->data['old_values_locales']->diff($this->data['current_values_locales']) as $locale) {
            $this->data['entry']->setTranslation($this->data['revision']->key, $locale, $this->data['old_values'] [$locale]);
        }
    }

    private function updateAllLocalesThatAreCommonInOldAndCurrentVersion()
    {
        foreach ($this->data['old_values'] as $locale => $revisionTranslation) {
            if( $revisionTranslation !=  $this->data['entry']->getTranslation($this->data['revision']->key, $locale)) {
                $this->data['entry']->setTranslation($this->data['revision']->key, $locale, $revisionTranslation);
        	}
        }
    }

it is ugly but do the trick
