I have an AsyncThunk method named likePost when a user clicks like on a post it will send this action via dispatch. The method runs fine, and in my database the Post is updated successfully, but I can't get Redux to update the Post that is liked during the .fulfilled method.
Here is what I'm currently working with:
// shoes = [{_id: '', title: '', likes: []}, ...{}]
export const likePost = createAsyncThunk(
'posts/likePost',
async (payload, { rejectWithValue }) => {
try {
const response = await userTokenAxios.post(`/${payload}/like`);
return response.data;
} catch (error) {
return rejectWithValue(error.response.data);
}
}
);
[likePost.fulfilled]: (state, action) => {
const post = state.posts.find((post) => post._id === action.payload._id);
post.likes.push(action.payload.user);
},
Instead of finding the post, get the index for that object in state.posts const post = state.posts.find((post) => post._id === action.payload._id);
const postIndex=state.posts.findIndex((post)=> post._id === action.payload._id);
Now you can push the user in likes array:
state.posts[postIndex].likes.push(action.payload.user)
