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
@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
