I have a problem using orWhere in eloquent.
I have a team, and this team has som profiles. I want to get all the profiles which have the status = 1 or status = 2. But I cant get it to work.
My code is like this:
$profile = $this->team->profiles->where('status', 1)->find($id);
Thanks:-)
Instead of calling where() on the result of the relationship (which I assume is a collection) you should call it on the relationship object itself, which you can get by calling the function that defines this relation:
$profile = $this->team->profiles()->whereIn('status', [1,2])->find($id)
I also suggest to use whereIn instead of two wheres...
You can use, the Where In function with An Array
$profile = $this->team->profiles->whereIn('status', [1, 2])->get();

I have an accessor/attribute ( public function getGalleryAttribute() ) that adds an array of images to the model
I used to eager load this with: protected $appends = ['gallery'] , but I got rid of it to be able to control when I want to append the gallery or not.
I can append the gallery to a single model:
$event = Event::find(126)->append('gallery');
But how do I manually append an accessor when there is more than one result?
This doesn't work:
$events = Event::all()->append('gallery');
return $events;
error:
BadMethodCallException: Method Illuminate\Database\Eloquent\Collection::append does not exist
If you are using Eloquent 5.5 or later, you can use Collection::each to append to each item:
$events = Event::all()->each->append('gallery');
You should also look into Eloquent: API Resources to define alternative serialization options for the same model.
So... I've inherited this rather large project based on Zend Framework 1.12 and a feature that I'm trying to add involves a more complex database operation than what I'm used to doing with the project. I'm extremely new to Zend Framework, or MVC for that matter. I found an answer for Zend Framework 3 which would have been perfect but I have to make do with this version.
The function basically builds a Zend_Db_Select based on various parameters and the feature I'm trying to add will involve joining two different tables and checking if a specific combination exists in one or the other.
Here's what I have so far:
//SQL that I'm trying to do. Assume table1 and table2 are already joined.
//Ignore the imperfect syntax. I'm trying to get the concept across.
//SELECT * FROM (table1 joined to table2 by a common key)
//WHERE ( (table1.column1 = myParam1) AND (table1.column2 = myParam2) )
//OR WHERE ( (table2.column1 = myParam1) AND (table2.column2 = myParam2) )
public function buildSelect($params){
//Zend code starts here
//This one starts the Zend_Db_Select
$select = $this->select();
$table1Name = get_table_name_from_object($table1);
//lots of preexisting code here
//my code starts here.
$table2Name = get_table_name_from_object($table2);
$select->join($table2Name, "$table1Name.key = $table2Name.key", array('column1', 'column2', 'key');
//After I wrote this, I instantly realized why it won't work the way I intended it but putting it here to show what I tried at which point I got stuck.
$select->where("($table1Name.column1 = ?) OR ($table2Name.column1 = ?)",$params[1]);
$select->where( "($table1Name.column2 = ?) OR ($table2Name.column2 = ?)", $params[2]);
//more preexisting code below.
return $select
}
Obviously, if I tried this as is, the program will happily return results that include a combination of, say, an entry where param1 is in table1.column1 and param2 is in table2.column2.
I received some feedback from a friend and posting here for posterity.
They noticed my code already contains parentheses and recommended that I simply take advantage of orWhere() then write it like this:
$select->where("($tableName1.column1 = ?", $params[param1])
->where("$tableName1.column2 = ?)", $params[param2]);
$select->orWhere("($tableName1.column1 = ?",$params[param1])
->where("$tableName2.column2 = ?)",$params[param2]);
With dapper, I can do batch execute for Stored Procedures, something similar to:
connection.Execute(#"
exec sp1 #i = #one, #y = #two
exec sp2 #i = #three",
new { one = 1, two = 2, three = 3 });
However, the only means of retrieving data that I have seen till now is by using
results.Read<Type>()
What if the results don't map to an object? For instance, I am writing "generic" code to execute any SP with variable in/out parameters & result sets.
Thanks
What API do you want? If you can process the grids separately: do that:
using(var multi = connection.QueryMultiple(...))
{
while(!multi.IsConsumed) {
// ...
}
}
where ... has access to:
Read() for dynamic rows - noting that each row also implements IDictionary<string,object>
Read<T>() for typed rows via generics
Read(Type) for typed rows without generics
Read<DapperRow>() (actually, this is just the T that Read<T>() uses to implement Read(), but perhaps more convenient), which provides slightly more access to metadata
If you want to drop to a raw IDataReader, do that:
using(var reader = connection.ExecuteReader(...)) {
// whatever you want
}
With regards to parameters: the DynamicParameters class provides much richer access to parameter control, including parameter-direction etc.
I'm trying to create a new OpportunityProduct using this rest call:
XRMServices/2011/OrganizationData.svc/OpportunityProductSet
{"ProductId":"ef71ce8e-1ef3-e211-b252-984be17c47e4","Quantity":123,"ProductDescription":"Added from code - TEST123","OpportunityId":"8bdb3525-7274-e311-a90b-6c3be5be5f78"}
The call returns:
The request should be a valid top-level resource object.
This indicates that my arguments is not correct. I see to possible reasons for this:
I'm missing some required properties (How can I figure out which is required?)
It is not possible to do using rest
(both guids are returned via other call and should be correct)
Any help would be great!
Thanks

For lookup references to other entities you need to specify both the GUID and the type. You also need to include the UOM when creating an Opportunity Product based on an existing Product. Your object should look something like this:
var entity = {};
entity.Quantity = parseFloat(4).toFixed(2);
entity.OpportunityId = {
Id: '69BB2236-B57F-E311-BB6D-6C3BE5A881A4',
LogicalName: 'opportunity'
};
entity.ProductId = {
Id: 'C8138483-DF81-E311-B542-6C3BE5A8362C',
LogicalName: 'product'
};
entity.UoMId = {
Id: 'BE0FB859-7E90-4B3E-B501-3AB3CD4DC8FC',
LogicalName: 'uom'
};
I'm trying to use a select object to filter the results of a many to many rowset. This call works great:
$articles = $this->model->findArticlesViaArticlesUsers();
This however does not:
$articles = new Default_Model_Articles();
$articleSelect = $articles->select();
$articleSelect->where("status = 'published'")
->order("date_published DESC")
->limit(1);
$articles = $this->model->findArticlesViaArticlesUsers($articleSelect);
That throws the following error:
exception 'Zend_Db_Select_Exception'
with message 'You cannot define a
correlation name 'i' more than once'
I can't figure out how to successfully get "articles that have the status of 'published'" using the magic many-to-many relationship (nor findManyToManyRowset). I'm at the end of my rope and thinking of just writing the sql manually. Any ideas?
When defining the select statement, you must use the same object that you call findManyToManyRowset (or whatever magic function you use) on.
Ex:
$articles = new Default_Model_Articles();
$user = $articles->find($userId)->current();
$select = $user->select();
$select->where('status = ?', 'published');
$articles = $user->findArticlesViaArticlesUsers($select);
Notice the select statement and findArticlesViaArticlesUsers are both extending $user. Thats the key.
I think you've misunderstood how the relationships work.
See this manual page - you should call the magic method, findArticlesViaArticlesUsers, on a Row object. In this case, I think you want to find a User, and then call findArticles... on that.
