Yii2 GridView implement Filter and Sort for Values for related Table of foreign Table

Question

I have 3 Tables:

CREATE TABLE tabCve
(
    intCveID INTEGER NOT NULL AUTO_INCREMENT,
    strNumber VARCHAR(20) NOT NULL,
    fltScore FLOAT(0),
    strDescriptio         


        

Answer 1

In your seachModel you need public var for filter ..

not need select because this are provide by find.. and is better rearrange the code below

$query->select(["intCveID","strNumber","fltScore","strDescription","datImported","intCvePhaseID","intCveTypeID",'progress.intProgressCategoryID']);
$query->joinWith("phase");
$query->joinWith("type");
$query->joinWith("progress");
$query->Where(['not like', 'strDescription', '** RESERVED **%', false]);
$query->andWhere(['not like', 'strDescription', '** REJECT **%', false]);

in another way like suggested in this doc

http://www.yiiframework.com/wiki/621/filter-sort-by-calculated-related-fields-in-gridview-yii-2-0/

http://www.yiiframework.com/wiki/653/displaying-sorting-and-filtering-model-relations-on-a-gridview/

For

->andFilterWhere(['like','tabProgress.tabCategory.strCategory', 
        $this->intCveTypeID])

the samples provide in the link above suggest the use of getter for retrieve the column you need and the use of this getter also in andFilterWhere

this way :

in your Model you already have a

public function getCategory()
{
    return $this->hasOne(TabCategory::className(),
     ['intCategoryID' =>   'intProgressCategoryID']);
}

then you can buil a getter for for strCategory

public function getStr_category() {
    return $this->category->strCategory;
}

at this point you can retrieve the data in you modelSearch with

->andFilterWhere(['like','str_category', $this->intCveTypeID])
