I'm a beginner in symfony/twig and i need help to understand how to access variable from a join entity in twig
I've 2 entities : Avdert with a one-to-one relationship with the entity Image
I created an index.html.twig where all my Advert are listed using the variable $listAdverts it's OK I've the list of all my adverts
I want to display a small image near each of my Advert, if I look using dump what's in advert.image I've id and url of image it's OK.
So I thought that as I just needed to use advert.image.url to access the url of the image, but instead I'm getting this error:
"Impossible to access an attribute ("url") on a null variable"
I'm missing something but what ?

I want to create relations between Post and Tag as follows.
Post has many Tags (one-to-many)
Tags have and belongs to many Posts (many-to-many)
I created collection types for Post and Tag.
Set them accessible for public user.
I created 1 post with 3 tags.
Now, when I try to see them at http://localhost:1337/api/posts
I don’t see nested elements, i.e. tags…
Am I missing anything ?
And lastly, I was not able to create Many-to-Many relations between Post and Tag with the following error.
I understand that Tags field already exists, but I thought this is how supposed to be set.
I got reply from Strapi forum, so decided to share here.
https://docs.strapi.io/developer-docs/latest/developer-resources/database-apis-reference/rest/populating-fields.html
According to the docs above, to pull (in my case) 1st level nested elements I have to add populate[0] parameter like so:
http://localhost:1337/api/posts?populate[0]=tags
For the first time, I am working on userfrosting, it is based on MVC. So I know how the things are working but my issue is now, I want to call the one of the model to find the particular userid ie. Employee::find(1)
I want to get the username for the particular id, as I am running a for loop to I will be getting different id.
How can I call the model in my template twig?
I would like to create work order using escalation once the asset is moved to some other location (like REPAIR) using move/modify. I do understand that we can trigger CREATEWO however I am not sure on how to set the values on some fields in work order like worktype, workact , etc. Also I am unable to pick the correct record which has performed move modify ( unable to fetch the exact record using ASSETTRANS table).
Let me know if anyone has done this before, thanks in advance!
It sounds like you have an Escalation calling an Action that calls the AppAction CREATEWO. Assuming that's correct..
First, create a Relationship in DB Config between the ASSET object and WORKORDER that will find the most recent work order against this asset. You can look at the NEWWORKORDER relationships on WORKORDER and TICKET as an example. For reference, I will assume you name this relationship MYNEWWORKORDER.
Next, create some Actions against the ASSET object that use MYNEWWORKORDER.<ATTRIBUTENAME> in the Parameter/Attribute field, where <ATTRIBUTENAME> is the name of the attribute (e.g. WORKTYPE) you want to supply a value for in the Value field.
Once that is done, create an Action of type Action Group where CREATEWO is the first member and the Actions you just made are the succeeding members.
Finally, update the Escalation to call your new Action Group instead of the numbered one that the Escalation application created for you.
I'm trying to create a content part in Orchard that will perform a request to a web server and display the results of the request. The problem I'm running into is that my part requires no user input and thus I have left the part and part record classes empty. I have a Migrations.cs file that adds a description to the part and makes it attachable as well as creates a content item with the part attached to it. When I go to create a new instance of my content type it tries writing to the database and fails. How do you create a content part in orchard that doesn't try to save to the database? Thank you.
The actual error I receive is:
null id in Orchard.ContentManagement.Records.ContentTypeRecord
I'm pretty sure you don't need to create new table since there are many parts which don't have any in Orchard. Try to remove MyCustomPartRecord.cs and change MyCustomPart.cs
public class MyCustomPart : ContentPart<MyCustomPartRecord>
to
public class MyCustomPart : ContentPart
Then just add driver and view and you should be good without extra tables ... In theory :D
The answer to my problem is even when your part ins't actually saving anything in the database you still need to include a table for the part so it can store the id. I just added the following to my Migrations.cs file and it fixed the problem.
SchemaBuilder.CreateTable("MyCustomPartRecord",
table => table
.ContentPartRecord()
);
I have pages in a pages library on a publishing site which have a managed metadata (taxonomy) field in their content type. I want my custom search webpart to read the taxonomy set on its parent page (I can do this fine) and then query against a specific scope using only the selected tags of the parent page as the filter (no keyword necessary).
I have tried to set FixedQuery = “owstaxIdMetadataAllTagsInfo=#0[TERM GUID]” of my CoreResultWebPart with no success... I actually gave up after I was getting 0 results and am now trying to just perform a FullTextSqlQuery.
Unfortunately it seems that even though pages with the managed metadata field are successfully being indexed, the managed property owstaxIdMetadataAllTagsInfo has no data in the results! I went ahead and made the property searchable/queryable and the property value is null.
Can you anyone confirm that I should be getting values from that managed property when there is indeed a managed metadata field on the page that is populated with data?
Note: I have tried to make my own managed property based on the managed metadata field in my site's content type -- same results.
I don't think - owstaxIdMetadataAllTagsInfo returns anything. I tried adding it to my result web part's Diaplay properties > fetched properties and got a property not recognized...related error.
So I created a separate metadata property for 'enterprise keywords' i.e. 'TaxKeyword. You need to ensure that you check the checkbox - 'Reduce storage requirements for text properties by using a hash for comparison' otherwise no results will be returned for that peroperty is you use LIKE predicate with fulltextsql.
