I have created one collection called article and make a component Related_Article inside that i have given the relation to this article but i want that admin only put 3 Related_article after that the strapi shows an error or some message that you couldn’t add more and i am findining every possible solution but it doesn’t work
Help me if you have anything.
I think you want to modify the api::article.article 's create() function logic. and you can add a new customize controller. here is the docs: Backend customization - Controllers - Strapi Developer Docs and there are example in docs.
// path: ./src/api/article/controllers/article.js
const { createCoreController } = require('@strapi/strapi').factories;
module.exports = createCoreController('api::article.article', ({ strapi }) => ({
async create(ctx) {
console.log(ctx)
// you own create logic code here
// find related article count of ctx.state.user.id, if > N then return message
}
})
)
Hope it can help you
Thank you so much i think it solves my problem
Sorry to disturb you but you can help me with logic because i failed when actually use the logic
const { createCoreController } = require(’@strapi/strapi’).factories;
module.exports = createCoreController(‘api::blog.blog’ , ({ strapi }) => ({
async create(ctx) {
// some logic here
const response = await super.create(ctx);
// some more logic
console.log(response , "response");
console.log(ctx.request.body.data.Related_Blogs);
const count = await strapi.db.query(ctx.request.body.data.Related_Blogs).count();
console.log(count, "ctx");
return response;
}
}));
Hope it helps to crack the logic
I will have a try later. maybe some hours later. @Devarshivaidya
@Devarshivaidya I think the code you want to get maybe like under:
const { createCoreController } = require('@strapi/strapi').factories;
module.exports = createCoreController('api::article.article',
({ strapi }) => ({
async create(ctx) {
const response = await strapi.service('api::article.article').find({
filters: {
user: { // this filter linked user, you also can use createdBy
id: ctx.state.user.id
}
}
}).then(
res => {
if (res.results.length >= 3) {
return "You have already created 3 article"
}
}
)
// if not great than 3, then create article, if true return the message
const finalRes = response ?? super.create(ctx)
return finalRes
}
})
);
you can find here and run online
GavinXue/strapi-study-cases: strapi use cases when study, maybe it can help someone else.
Ok, and the second part of the question, how to make this custom controller restriction reflected in the Strapi UI?
