Pluck id (integer) cast to string Laravel
问题 While plucking from a database, I get id as strings. $alphabets = new Alphabet(); return $alphabets->pluck('name', 'id'); Output { "1": "Apple", "2": "Ball", "3": "Cat" } Expected { 1: "Apple", 2: "Ball", 3: "Cat" } But, when I reverse ID and name , return $alphabets->pluck('id', 'name'); I get id as integer. { "Apple": 1, "Ball": 2, "Cat": 3 } I'm not sure what's happening behind the scene. But how can I get ID in integer ? Actually, old flash session doesn't set value because of 1 vs "1" in
Using Laravel's pluck method without an associative array
问题 Let's say I've got an Article s collection, and I want to fetch the popular articles. So first, I make a scopePopular() method in the Article method. Very simple. Now I want to fetch their id s, so I'll do this: Article::popular->pluck('id'); The result will be an associative array: [ 0 => 1, 1 => 34, 2 => 17 ... ]; I want to get a normal array, without the keys, Like: [1, 34, 17] I know I can just do something like this: array_values(Article::popular->pluck('id')); But I believe Laravel has
Using Plucked Values in Ruby on Rails
问题 Given a model named Album, I want to use the values I pluck. For starters, I want to try to print the values. How can I do this? Here is my current code: my_arr = Album.where(title: "Greatest Hits", artist: "The Beatles").pluck(:publisher, :year_published) puts my_arr[0][0].to_a To make things even simpler, how would I retrieve any value at all, so that I could place it into a normal variable? I'm using Rails 4 with SQLite3. 回答1: pluck already returns an array - you do not need to manipulate
Neo4j gem - Plucking multiple nodes/relationships
问题 This may not be possible as it is right now but I have a query like so events = Event.as(:e).where("(( e.date_start - {current_time} )/{one_day_p}) < 1 ").users(:u, :rel).where("rel.reminded = {reminded_p}" ).params(reminded_p: false, one_day_p: one_day, current_time: time).pluck(:e,:u, :rel) The goal is to obtain the events where the start_date is less than a day away. Hypothetically I've tried to pluck the event, the user and the relationship. I need to do a different action with each. I

Pluck associated model's attribute in Rails query
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: In my rails app, collections have many projects , and projects have many steps . I'd like to grab all the ids of steps in a collection's projects, and I'm wondering if I can do it all in one query. For example, I know I can do the following step_ids = [] @collection.projects.each do |project| project.steps.each do |step| step_ids << step.id end end But is it possible to do something like the following: @collection.projects.include(:steps).pluck("step.id") // syntax here is not correct 回答1: Try this: Step.joins(:project).where(projects: {
In PHP, is there a function that returns an array made up of the value of a key from an array of associative arrays?
问题 I'm sure this question has been asked before, my apologies for not finding it first. The original array: [0] => Array ( [categoryId] => 1 [eventId] => 2 [eventName] => 3 [vendorName] => 4 ) [1] => Array ( [categoryId] => 5 [eventId] => 6 [eventName] => 7 [vendorName] => 8 ) [2] => Array ( [categoryId] => 9 [eventId] => 10 [eventName] => 11 [vendorName] => 12 ) My hoped for result out of: print_r(get_values_from_a_key_in_arrays('categoryId', $array)); [0] => 1 [1] => 5 [2] => 9 I'm just
