GridView::widget error array_merge(): Argument #2 is not an array

arthurkushman commented 7 years ago

What steps will reproduce the problem?

by passing the object to GridView::widget method like this:

\yii\grid\GridView::widget(
                [
                    'layout'       => "{items}\n{pager}",
                    'dataProvider' => $list,
                    'columns'      => $attributes
                ]
            );

with $attributes not only the array, but an object. Check algorithm can detect an array, but can not an object and crushes.

What is the expected result?

The grid table should be full-filled and rendered on the page

What do you get instead?

An error

What is your $attributes variable?

arthurkushman commented 7 years ago

What is what? Content or You need the print_r here? It is an array 100%, because there is a check with is_array($attributes) code:

        if (empty($attributes) === false && is_array($attributes)) {
            echo \yii\grid\GridView::widget(
                [
                    'layout'       => "{items}\n{pager}",
                    'dataProvider' => $list,
                    'columns'      => $attributes
                ]
            );
        }

It might be an array itself but what does it contain?

arthurkushman commented 7 years ago

That's what I've talked about, ok - here it is:

The overall content is much bigger, so the above is an example of upper content.

As I said, in structure there are objects which breaks GridView functionality.

alex-code commented 7 years ago

How have you constructed the $attributes array? The first bit you've shown doesn't look right to me.

[
  [
   'class' => 'yii\grid\SerialColumn'
  ],
  'attribute' => 'errorContainedPercent',
  'format' => 'raw '
]

I've found the answer now, sorry for disturbance - I'm closing this thread.
