QUESTION
I got the following Entities:
- A User Entity, it has OneToMany Products and OneToMany Images
- A Product Entity that has ManyToMany Images
- An Image Entity, having the ManyToOne to User, and the (inverted) ManyToMany Products
The Images connected to the Product are also always connected to the same User Entity too.
I want to display for the Current User the Products and their Images in a Table.
- For this, the User is loaded by the User Provider. (1 Query)
- Then it gets the N Products for the User (1 Query)
- Then it ask Images joined by the ManyToMany table which Images are connected to the Products (N Queries)
The Last Queries I want to optimize somehow if able. My thought because I already know what kind of Images there will be because of the User OneToMany Relationship.
What could I do it make it better? Try to build my own Query? My own Hydrator? Maybe Caching of the Images Entities will be enough?
I tried making the Entities and their relationships Cacheable but that doesn't seems to reduce the amount of queries.
...ANSWER
Answered 2021-Dec-15 at 09:27From what you explain:
You need to load from both user side (product and image). It can happen to load image not linked to the user (and product not linked to the user).
Your problem com from the many to many between product and image, that will force you to load image from product and not from user.
The solution would be to change your database to match this:
where the linked table containing all 3 foreign key has a uniq constraint on all 3. This way, you just have to load everything in 1 query from user if you use DQL or SQL.

hellow every one i migrated gitlab-ce into a new instance with new domain name using backup/restore
my problem : when i click a project it gives me "500 Whoops, something went wrong on our end "
i installed the same gitlab-ce version in the new host which is 13.6.2
my gitlab status
...ANSWER
Answered 2021-Oct-28 at 16:29To fix this problem I had to migrate gitlab-secrets.json
from /etc/gitlab
too, because this file contains the database encryption key, CI/CD variables, and variables used for two-factor authentication.
If you fail to restore this encryption key file along with the application data backup, users with two-factor authentication enabled and GitLab Runner lose access to your GitLab server.

QUESTION
I was working on Laminas or Zend framework 3 and I tried to use annotation to geneate form
But get this message
...ANSWER
Answered 2020-Sep-02 at 09:13did you check the existence of AnnotationManager in your vendor? It should be under vendor/laminas/laminas-code/src/Annotation/AnnotationManager.php
Like you can see, it's located in a seperate package called laminas/laminas-code. Depending on your composer require statements it is not loaded by default.
Do you have any output with composer why laminas/laminas-code
QUESTION
I have a question regarding rehydrate of the tweet's text. Any help would be appreciated.
This is the source of my data; which is about corona tweets:
I have downloaded a data set from it which is in the photo (named 01-feb-2020)
Then, I filter this data to show me the only tweets from 'GB' which is almost 24000 tweets
I have used twarc to hydrate my tweets' text as below :
first, install twarc using pip
then, type this in the command line: twarc configure
then, inter consumer key and secret key
then, write a command:
...ANSWER
Answered 2020-Aug-05 at 18:24The Tweet ID collection method (which was copy-pasting ) was not correct. After writing a proper code to save tweet ID into text file, the problem has been solved.
Also, Andy Piper mentioned the same thing in the comment part which I copy past here.
How are you getting from JSON format downloaded, into a CSV format? I'm wondering whether the Tweet ID values are valid. – Andy Piper 5 hours ago
I've managed to reproduce this now, and I believe that in the process of converting your JSON input to CSV / Excel to a list of Tweet IDs to hydrate, you are probably using JavaScript (?) and the Tweet IDs are losing their accuracy. The clue was when I noticed all of the Tweet IDs ending in 0000 in my Excel column. You'll need to use a more precise method of getting the Tweet IDs into twarc
QUESTION
from CDAP documentation exists an HTTPS post-run plugin to trigger pipeline start based on the successful execution of another pipeline (Scheduling). I'm trying to use this functionality in GCP Data Fusion but the plugin even if installed (because I can see it from Control Center) seems to be not available.
I also tried to install manually the plugin HTTP Plugin v2.2.0 as stated in the documentation but has only sink and source action. Also if I try to use the plugin an error is displayed
HTTP Properties 1.2.0 (No widgets JSON found for the plugin. Please check the documentation on how to add.)
this error seems related to the fact that Data Fusion is trying to use version 1.2.0 (the one already installed) with properties of version 2.2.0.
Any suggestions on how to solve this issue?
Update
I can see the two vesions http-plugin from Control Center
but I cannot set the version
Problem about http plugin hasn't been solved but I found the existence of pipeline trigger to execute pipeline based on status of another pipeline, this feateure is only available with Enterprise edition.
...ANSWER
Answered 2020-Jul-13 at 17:35Depending on the version of the you Data Fusion instance, it may still be defaulting to the old version of the plugin. To select the new version of the plugin you should:
- Navigate to the Studio
- Hover your mouse over the HTTP plugin in the sidebar
- After a second or so, a box will appear with the plugin details. You will see the current version of the plugin and a button beside it that says "Change", click on this button. If you don't see this button that means you only have one version of the plugin in your instance.
- You will see a list of all the versions of the plugin in this instance, select the one you want. The version you select will be the new default version.
You should now be able to use v2.2.0 of the plugin.

QUESTION
I have an Address entity which is bind to a ZF / Laminas Form.
Some properties are defined. Such as street, country, ....
...ANSWER
Answered 2020-May-26 at 11:06I think you don't have a problem with Doctrine or hydration, you've a problem with type-conversion.
When that value comes from a Laminas\Form\Form
object, then you should use the InputFilter
to convert the value to bool with a filter. The ObjectHydrator
from should then take the value from the input filter.
Let's take a look at my example (for the sake of simplicity I don't use Doctrine here):
