问题描述

使用背包在项目中完成其任务(自动添加其功能)的问题.

解决方案

注释自动添加CrudTrait，然后按照@OMR的建议手动添加这里.

Problem using Backpack to do its thing (automate adding its features) to the project.

From the tutorial:

Mine:

PS C:\Apps\xampp\htdocs\cofour-intern>  php artisan blueprint:build 
...
PS C:\Apps\xampp\htdocs\cofour-intern> php artisan backpack:crud Product     
Controller created successfully.

解决方案

Commenting out the automated adding of CrudTrait, and then adding it manually as recommended by @OMR here, works. Presumably should not be necessary, but now the command calls work in the regular order:

blueprint:build
backpack:build

CrudModelBackpackCommand.php (line 75):

        // if it does not have CrudTrait, add the trait on the Model

        $classDefinition = 'class '.$this->getNameInput().' extends';

        // foreach ($file_array as $key => $line) {
        //     if (Str::contains($line, $classDefinition)) {
        //         if (Str::endsWith($line, '{')) {
        //             // add the trait on the next
        //             $position = $key + 1;
        //         } elseif ($file_array[$key + 1] == '{') {
        //             // add the trait on the next next line
        //             $position = $key + 2;
        //         }

        //         // keep in mind that the line number shown in IDEs is not
        //         // the same as the array index - arrays start counting from 0,
        //         // IDEs start counting from 1

        //         // add CrudTrait
        //         array_splice($file_array, $position, 0, '    use \\'.$this->crudTrait.';');

        //         // save the file
        //         $this->files->put($path, implode(PHP_EOL, $file_array));

        //         // let the user know what we've done
        //         $this->info('Model already exists! We just added CrudTrait on it.');

        //         return false;
        //     }
        // }

        $this->error('Model already exists! Could not add CrudTrait - please add manually.');

        return false;
    }

I likely moved some file out of place, but I am not sure which one...

The case has also been opened as a bug on their github here.
