I have explained whole issue here https://github.com/marmelab/react-admin/issues/5142 . But as far as the stackoverflow community is more active, I mention the issue here too.
Please explain me, why this sample code is working properly
<ReferenceInput label={"Specification"} perPage={20} source={"specificationName"}
reference={ResourceNames.SPECIFICATIONS}>
<SelectInput optionText={"name"}/>
</ReferenceInput>
while this code is showing the "Associated reference no longer appears to be available" error message.
<ReferenceInput label={"Specification"} perPage={20} source={"specificationName"}
reference={ResourceNames.SPECIFICATIONS}>
<SelectInput optionText={"name"} optionValue={"name"} />
</ReferenceInput>
The only difference between above given examples - is the optionValue property passed to SelectInput. What's wrong with it? I don't want my SelectInput to use ID as a value... How the optionValue property is related to the above mentioned error message?
Please help! Thank you in advance
I have found a solution. React-Admin requires the id for resources identification.
But if you need a custom identifier for your resource then have a look at the article below
See https://marmelab.com/react-admin/FAQ.html#can-i-have-custom-identifiersprimary-keys-for-my-resources
This error can occur also if your model filter doesn't accept an ids attribute, observed in the web console.
I ended up in this situation because I based my schema off the schema provided in the readme of ra-data-graphql-simple.
To solve, I added the ids property to the type filter in the graphql schema.
PS - if you're bootstrapping like I was, it will be time to swap out the Edit and List Guessers for components that make use of a reference field

Hello Support I can't get the String from a Component. I did this with 2 ways with bad results.
TextComponent textComponent = (TextComponent) item.displayname;
return textComponent.content();
The result of this is a error with Casting
and
return PlainTextComponentSerializer.plainText().serialize(item.displayname);
The result of this is Literaly "chat.square_brackets" which is weird.
Please Help. Thanks
I also was having trouble with this. Here's what I found to work for me. Full disclosure that I'm developing my plugin on the PaperMC 1.16 fork and not Spigot. So it's possible that this may not work for you, either because it isn't a part of Spigot or because you are working in a version that this feature is not a part of.
To start, I would first check to make sure that we are both on the same page. For me, the component objects being used are from a package called net.kyori.adventure.text if yours are not provided by this package I don't know that this solution will work for you.
Also as mentioned by others, accessing the displayName directly on the ItemStack isn't going to give the desired results. Instead, you need to do itemStack.getItemMeta().displayName(). This method should then return a net.kyori.adventure.text.Component; once you have the component you need to serialize it using one of the serializers from the previously mentioned package.
That will look something like this:
Component itemDisplayName = itemStack.getItemMeta().displayName()
PlainComponentSerializer plainSerializer = PlainComponentSerializer.plain();
String itemName = plainSerializer.serialize(itemDisplayName);
The package that the serializer is from is: net.kyori.adventure.text.serializer.plain.PlainComponentSerializer
I don't understand how you can access to the displayname field in ItemStack in the Spigot API.
You should use ItemMeta to manage display name. To get the item meta, you should use ItemStack#getItemMeta.
Don't forget to check if the item as a meta with hasItemMeta. You can also use hasDisplayName to be sure that the display name is valid.
[PROBLEM SOLVED]
Hey folks I need your help on a symfony project.
I have two entities, "article" and "image", article can have several images so I made a relationship OneToMany on the article side and ManyToOne on the image side. Doctrine generates for me an "article_id" column on the image table.
I made a form to create an article with one or more images... however when I execute it I have an error that is thrown :
An exception occurred while executing 'INSERT INTO image (url, alt, article_id) VALUES (?,?,?) 'with params ["jpeg", "untitled.jpg", null]: SQLSTATE [23000]: Integrity constraint violation: 1048 Column' article_id 'can not be null.
When I look to the profiler logs debug, I can see that I have an "INSERT INTO article[...]" (so the article is created with an ID ?) and just after this I have the famous "INSERT INTO image[...]" where the error occurs.
Thank you for your help.
EDIT In bold you will find the lines I added to solve this problem.
I added into the ArticleType form, in the images collection options this :
'by_reference' => false
And I added to the addImage method into the Article entity this :
$image->setArticle($this);
$this->images->add($image);
This is a very common question but surprisingly difficult to search for. In fact the first ten or so search results had incorrect answers.
In any event, you need to make sure that image is linked to the article.
class Article
public function addImage($image) {
$this->images[] = $image;
$image->setArticle($this); // ADD THIS
I think #Cerad's answer is very wrong, although I can't blame him because OP hasn't posted enough code, don't be shy with it, we're here to help. It also helps to briefly mention if you're just starting out (as I suspect you are) as it will help us gauge whether its a novice problem or something deeper.
Since I'm assuming it's a novice problem here is the novice solution.
With they way you've mapped (which I believe is correct) you are basically telling Doctrine to Tell your RDBMS (MySql/MariaDB/PostgreSQL) that an article CAN have many images, but an image MUST belong to an article.
This means that if you attempt to save an image without specifying the owning article, it will throw an error.
This is what I think you are doing evident in the line
(url, alt, article_id) VALUES (?,?,?) 'with params ["jpeg", "untitled.jpg", null]
the value "null" is where the issue is coming about because you are not specifying the owning article.
You have 2 options
1.) When saving image, if you have the article object at hand just do
$image->setArticle($article);
2.) When saving the image, if you have the article_id at hand just do
$image->setArticle($em->getReference('AppBundle\Entity\Articles', $article_id));
You must follow one of the above when saving an image directly.
My general experience has been that Doctrine does a really good job of generating entities from command line that you really don't need to change much unless adding some advanced functionality like second_level_cache or MySQL point type.
Cheers.
The problem is that when you submit your form, the first image is attached to the article but the others are not, so you get an SQL error.
You have to do a "foreach loop" for every image and attched the article to each one.
Look here at the addAction function

Would like to ask on how you can get the id of the comodel inside the ir.actions.act_window.
See my source code: https://gist.github.com/renesansz/2642b02875475383605e
Currently, I cannot get the sprint_id.project_id.current_sprint reference since it's giving me an error of Uncaught Error: NameError: name 'sprint_id' is not defined. So what I wanted to happen is that upon opening the project it should add a default filter for the current sprint of the project.
Do I have any alternative for this kind of approach?
Tried doing domain, but still no luck solving the issue.
Try this: make related field and then use this field in xml view.
Another individual said this error is generally caused by "a widget template that is referencing a property via ${...} that doesn't actually exist in the widget."
I've researched and can't seem to find a way to resolve this error. Any advice or leads to help solve this issue? How do you FIND this bit of code to correct the issue?
Got some assistance from SitePen.
Here's the trace Stack -
**string.substitute/<()string.js (line 147) string.substitute()string.js
(line 141) ._updatePaginationStatus()Pagination.js (line 395)
.gotoPage/
return transform(value, key).toString();
instrum...tion.js (line 20)**
The Pagination was failing - potentially trying to pull data before it was actually there.
"Code is trying to do a string.substitute call, but the transformation you're trying to do isn't valid. It looks like the Pagination extension is failing on this. Given the number of steps related to Deferreds, it looks like something is trying to parse data before that data is available. For example, you have an async call, but are treating the data synchronously.
That said, when using the Pagination extension, I think you use the normal Grid rather than the OnDemandGrid."
I switched from OnDemandGrid to Grid - left pagination. Error still there. Switched back to OnDemandGrid - eliminated Pagination. Error Gone.
Also found this little note that I had overlooked in documentation: "Note that the Pagination extension is incompatible with OnDemandGrid, since each has its own way of dealing with collection ranges. Pagination should be mixed into Grid, not OnDemandGrid."

id is present in the params but does not save to the db. for example
[book.id:1, comments: good]
comments will save to db but book.id does not.
I need to figure out how to save params.book.id into the db column BOOK_ID that was created from the hasmany/belongsTo relationship.
By default value attribute of each element will be the result of a toString() call on each element. Setting it as optionKey allows the value to be a bean property of each element in the list.
Kindly change the select to
<g:form action="review">
<g:select name="book.id"
from="${item.Book.list()}"
value="${book?.id}"
/>
<g:textField name="bookreview" value="${params?.bookreview}" /><br>
kindly refer the below link
Grail example with optionkey
You have overwritten toString, therefore your books are always rendered by name and not id. If you remove your toString() method you will see the expected results.
If you want your select box work with the name, just add optionValue="name".
Well, it seems that I had misspelled a crucial parameter inside my domain. So the domain was expecting x and it was getting y. Thus the id was always null. It took me a while to spot it, and I was perplexed because I had previously successfully implemented ids in another project. Grails has some jira issues also that make one consider other possibilities, but this time it was my mistake.
