在模型和相关模型的领域中查询,使用或其中的多个 [英] Multiple where queries, using orWhere, in fields of model and related models
问题描述
我正在尝试添加一个功能,可以在过滤数据时使用逗号作为OR分隔符。我需要做一般,因为我有相当多的表,领域和关系。另外一些表是动态构建的。
添加模型自身字段的where子句的代码是:
foreach($ filters as $ column => $ filter){
$ q-> where(function($ q)use($ filter,$ model,$列){
$ first = array_pop($ filter);
$ q-> where($ model。$ column,'LIKE',%$ first%);
foreach($ filter as $ or){
$ q-> orWhere($ model。$ column,'LIKE','%$ or%);
}
});
}
这样可以预期。当尝试与关系领域做同样的事情时,唯一的区别是使用where和HAS并包含模型:
foreach($ filters作为$ column => $ filter){
$ q-> whereHas($ model,function($ q)use($ filter,$ model,$ column){
$ first = array_pop $ filter $;
$ q-> where($ model。$ column,'LIKE',%$ first%);
foreach($ filter as $ or){
$ q-> orWhere($ model。$ column,'LIKE',%$或%);
}
});
}
问题是如果我对关系字段进行过滤,它不起作用如预期。我怀疑它与哪里有一个sub / orWhere子句。这是我得到的输出
没有过滤器:
| ------------ + ----------------------------------- + ------------- ------------------------- |
|联系人ID |类型(联系SQL表中的字段)| Ecozone(生态区SQL表)|

当前模型的单个过滤器(正确):

|过滤器 - > | |巴士|

相关模型字段上的多个过滤器(不正确):

| ------------ + -------------------------------- --- + -------------------------------------- |
| 1 |经理|布什|
| 2 | |森林|
| 3 |工人| |
| ------------ + -------------------------------- --- + -------------------------------------- |
整个代码路径如下:
在控制器中:
返回联系人:: with(
'ecozone'
) - > where ($ q){
$ this-> set_filters($ q,'contact');
}) - > paginate($ count);
在BaseController中:
protected function set_filters($ q,$ current_model){
$ filters_array = $ this-> parse_filters();
if($ filters_array){
foreach($ filters_array as $ model => $ filters){
if($ model == $ current_model){
foreach($ filters as $ column => $ filter){
$ q-> where(function($ q)use($ filter,$ model,$ column){
$ first = array_pop ($ filter $)$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $
$ q-> orWhere($ model。$ column,'LIKE',%$或%);
}
});
}
} else {
foreach($ filters as $ column => $ filter){
$ q-> whereHas($ model,function($ q)use ($ filter,$ model,$ column){
$ first = array_pop($ filter);
$ q-> where($ model。$ column,'LIKE',%$第一个%);
foreach($ filter as $ or){
$ q-> orWhere($ model。$ column,'LIKE',%$ or%);
}
});
}
}
}
}
}
$ this-> filters是:
protected function parse_filters(){
$ filters = :获得( '过滤器');
$ filters = json_decode($ filters);
$ filters = array_where($ filters,function($ key,$ value){
return!empty($ value);
});
$ filters =(Array)$ filters;
$ has_filters =!empty($ filters);
if($ has_filters){
$ filters_array = [];
foreach($ filters as $ key => $ value){
$ value = explode(',',$ value);
array_set($ filters_array,$ key,$ value);
}
} else {
$ filters_array = false;
}
return $ filters_array;
}
并返回,我认为是正确的,以下数组。第一级是模型,第二是字段,第三是逗号分隔OR子句
Array(
[ecozone] => ; Array
(
[ecozone] => Array
(
[0] => bush
[1] => forest
)
)
[contact] => Array
(
[contact_type] => Array
(
[ 0] => manager
[1] => worker
)
)
)
过滤当前模型字段时使用的SQL的转储。这样可以预期:
array(size = 4)
0 =>
array(size = 3)
'query'=>字符串'select count(*)作为聚合从`contact`,其中`contact`.`deleted_at`是null和((`contact`.`physical_address` LIKE?或`contact`.`physical_address` LIKE?))'(length = 163)
'bindings'=>
数组(size = 2)
0 =>字符串'%add%'(length = 5)
1 =>字符串'%nana%'(length = 6)
'time'=>浮动1.67
1 =>
array(size = 3)
'query'=> string'select * from`contact`其中`contact`.`deleted_at`是null和((`contact`.`physical_address` LIKE?或`contact`.`physical_address` LIKE?))limit 10 offset 0'(length = 161)
'bindings'=>
数组(size = 2)
0 =>字符串'%add%'(length = 5)
1 =>字符串'%nana%'(length = 6)
'time'=> float 0.91
2 =>
array(size = 3)
'query'=> stringselect * from`ecozone`其中`ecozone`.`deleted_at`为null,`ecozone`.`id`(?
数组(size = 2)
0 =>字符串'1'(长度= 1)
1 => string'2'(length = 1)
'time'=> float 0.8
由相关模型字段过滤的SQL查询转储。这不按预期方式工作:
array(size = 4)
0 =>
array(size = 3)
'query'=>字符串'select count(*)作为聚合从`contact`,其中`contact`.`deleted_at`为null,((select select(*)from`ecozone`,`ecozone`.`deleted_at`为null和`contact`。 `ecozone_id` =`ecozone`.`id`和`ecozone`.`ecozone` LIKE?或`ecozone`.`ecozone` LIKE?和`ecozone`.`deleted_at`是null)> = 1)'(length = 301)
'bindings'=>
数组(size = 2)
0 =>字符串'%grass%'(length = 7)
1 =>字符串'%bush%'(length = 6)
'time'=> float 1.18
1 =>
array(size = 3)
'query'=> string'select * from`contact`其中`contact`.`deleted_at`为null,((select select(*)from`ecozone` where`ecozone`.`deleted_at`为null,`contact`.`ecozone_id` =` ecozone`.`id`和`ecozone`.`ecozone` LIKE?或`ecozone`.`ecozone` LIKE?和`ecozone`.`deleted_at`是null)> = 1)limit 10 offset 0'(length = 299)
'bindings'=>
数组(size = 2)
0 =>字符串'%grass%'(length = 7)
1 =>字符串'%bush%'(length = 6)
'time'=> float 0.89
2 =>
array(size = 3)
'query'=> stringselect * from`ecozone`其中`ecozone`.`deleted_at`为null,`ecozone`.`id`(?
数组(size = 2)
0 =>字符串'1'(长度= 1)
1 => string'2'(length = 1)
'time'=> float 1.38
你需要使用这样的东西您的一组过滤器:
`where(function($ q){$ q-> where() - > ();})`
使内部 wheres
包裹在(...)
,因为通过添加简单的或者你在/ / code>你会整个查询:
//您的第二个查询不正确的数组:
select * from`contact`其中`contact`.`deleted_at`是null和
((select select(*)from`ecozone` where`ecozone`.`deleted_at`为null
和`contact`.`ecozone_id` =`ecozone`.`id`
//这是你的第一个()
和`ecozone`.`ecozone` LIKE?
//这是orWhere,这使得查询错误
或`ecozone`.` ecozone` LIKE?和`ecozone`.`deleted_at`为null)
> = 1)limit 10 offset 0
您已经对顶级过滤器执行了此操作,b不在 whereHas
所以应该是这样的:
} else {
foreach($ filters as $ column => $ filter $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ )使用($ filter,$ model,$ column){
$ first = array_pop($ filter);
$ q-> where($ model。$ column,'LIKE' %$ first%);
foreach($ filter as $ or){
$ q-> orWhere($ model。$ column,'LIKE',%$ or%) ;
}
});
});
}
}
I have many tables (user facing, not SQL) with filter boxes per column. The columns have not only the tables' fields but fields of related models.
I'm trying to add a feature where one can use a comma as an OR separator when filtering data. I need to do it generally as I have a rather large amount of tables, fields and relations. Plus some tables are built dynamically.
The code that adds the where clauses for the models own fields is this:
foreach ($filters as $column => $filter) {
$q->where(function ($q) use ($filter, $model, $column) {
$first = array_pop($filter);
$q->where("$model.$column", 'LIKE', "%$first%");
foreach ($filter as $or) {
$q->orWhere("$model.$column", 'LIKE', "%$or%");
}
});
}
This works as expected. When trying to do the same thing with a relations fields the only difference is using whereHas and including the model:
foreach ($filters as $column => $filter) {
$q->whereHas($model, function ($q) use ($filter, $model, $column) {
$first = array_pop($filter);
$q->where("$model.$column", 'LIKE', "%$first%");
foreach ($filter as $or) {
$q->orWhere("$model.$column", 'LIKE', "%$or%");
}
});
}
The problem is that if I filter on a relations fields it doesn't work as expected. I suspect it has to do with whereHas with a sub where/orWhere clause. This is the output I get
No filters:
|------------+-----------------------------------+--------------------------------------|
| Contact ID | Type (Field in contact SQL table) | Ecozone (Field in Ecozone SQL table) |
|------------+-----------------------------------+--------------------------------------|
| Filter -> | | |
|------------+-----------------------------------+--------------------------------------|
| 1 | Manager | Bush |
| 2 | | Forest |
| 3 | Worker | |
|------------+-----------------------------------+--------------------------------------|
Single filter on current model (correct):
|------------+-----------------------------------+--------------------------------------|
| Contact ID | Type (Field in contact SQL table) | Ecozone (Field in Ecozone SQL table) |
|------------+-----------------------------------+--------------------------------------|
| Filter -> | man | |
|------------+-----------------------------------+--------------------------------------|
| 1 | Manager | Bush |
|------------+-----------------------------------+--------------------------------------|
Multiple filter on current model (correct):

| Filter -> | man, wor | |
|------------+-----------------------------------+--------------------------------------|

|------------+-----------------------------------+--------------------------------------|
| Filter -> | | bus |
|------------+-----------------------------------+--------------------------------------|
| 1 | Manager | Bush |
|------------+-----------------------------------+--------------------------------------|
Multiple filter on related model field (incorrect):
|------------+-----------------------------------+--------------------------------------|
| Contact ID | Type (Field in contact SQL table) | Ecozone (Field in Ecozone SQL table) |
|------------+-----------------------------------+--------------------------------------|
| Filter -> | | bus,for |
|------------+-----------------------------------+--------------------------------------|
| 1 | Manager | Bush |
| 2 | | Forest |

|------------+-----------------------------------+--------------------------------------|
The whole code path is below:
In controller:
return Contacts::with(
'ecozone'
)->where( function ($q) {
$this->set_filters($q, 'contact');
})->paginate($count);
In BaseController:
protected function set_filters($q, $current_model) {
$filters_array = $this->parse_filters();
if ($filters_array) {
foreach($filters_array as $model => $filters) {
if ($model == $current_model) {
foreach($filters as $column => $filter) {
$q->where(function ($q) use ($filter, $model, $column) {
$first = array_pop($filter);
$q->where("$model.$column", 'LIKE', "%$first%");
foreach($filter as $or) {
$q->orWhere("$model.$column", 'LIKE', "%$or%");
}
});
}
} else {
foreach($filters as $column => $filter) {
$q->whereHas($model, function ($q) use ($filter, $model, $column) {
$first = array_pop($filter);
$q->where("$model.$column", 'LIKE', "%$first%");
foreach($filter as $or) {
$q->orWhere("$model.$column", 'LIKE', "%$or%");
}
});
}
}
}
}
}
$this->filters is:
protected function parse_filters() {
$filters = Input::get('filters');
$filters = json_decode($filters);
$filters = array_where($filters, function($key, $value) {
return !empty($value);
});
$filters = (Array) $filters;
$has_filters = !empty($filters);
if ($has_filters) {
$filters_array = [];
foreach ($filters as $key => $value) {
$value = explode(',', $value);
array_set($filters_array, $key, $value);
}
} else {
$filters_array = false;
}
return $filters_array;
}
And returns, what I think is correct, the following array. First level is model, second is field, third is comma separated OR clauses
Array (
[ecozone] => Array
(
[ecozone] => Array
(
[0] => bush
[1] => forest
)
)
[contact] => Array
(
[contact_type] => Array
(
[0] => manager
[1] => worker
)
)
)

You need to use something like this for all your sets of filters:
`where(function($q){$q->where()->orWhere();})`
to make those inner wheres
wrapped in (...)
because by adding simple orWhere
you mess up whole query:
// your 2nd query in the incorrect array:
select * from `contact` where `contact`.`deleted_at` is null and
((select count(*) from `ecozone` where `ecozone`.`deleted_at` is null
and `contact`.`ecozone_id` = `ecozone`.`id`
// this is your first where()
and `ecozone`.`ecozone` LIKE ?
// and this is orWhere, which make the query wrong
or `ecozone`.`ecozone` LIKE ? and `ecozone`.`deleted_at` is null)
>= 1) limit 10 offset 0
You already did that for top level filters, but not in whereHas
So it should look like this:
} else {
foreach($filters as $column => $filter) {
$q->whereHas($model, function ($q) use ($filter, $model, $column) {
$q->where(function ($q) use ($filter, $model, $column) {
$first = array_pop($filter);
$q->where("$model.$column", 'LIKE', "%$first%");
foreach($filter as $or) {
$q->orWhere("$model.$column", 'LIKE', "%$or%");
}
});
});
}
}
