I am following a tutorial for strapi and am stuck at a part where I query for dishes belonging to a restaurant. I'm sure everything is set up properly with a one(restaurant) to many(dishes) relationship defined but the query doesn't work. I've traced it to the actual query which is:
query {
restaurant(id: "1") {
id
name
dishes {
name
description
}
}
}
which returns an error when I run it in playground. The query doesn't show any issues while I write it and doesn't allow me to write anything like:
query {
restaurant(where:{id: "1"}) {
id
name
dishes {
name
description
}
}
}
My database is mysql and the two tables look like this:
mysql> describe dishes;
+-------------+---------------+------+-----+-------------------+-----------------------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+---------------+------+-----+-------------------+-----------------------------+

These tables where auto generated by strapi.
The full error in playground is this:

Any idea why this is happening?
It seems this was a bug with the alpha.v20 and alpha.v21 versions of strapi. A bug fix has been published to solve it, an issue thread on github is here.

I have three tables topics, category(HowtoCategory::class), sections(Howto::class).
Multiple categories belong to one topic and multiple sections belong to one category.
Topic Has Many Category
Category Has Many Sections
Category Belongs to Topic
Sections Belongs To Category
Topic Has Many Sections Through Category
I want to search through the sections(Howto::class) but display the related topics. How can I access topics in the controller from my query search of sections? I dont want to access it in the view but in the controller.
Controller
public function index(Request $request)
{
if (request()->filled('search')) {
request()->fullUrlWithQuery(['search ' => null]);
$sections = Howto::search($request->search)->get();
$request = $request->input('search');
} else {
$sections = null;
}
return view('howto-pages.howto-main', [
'sections' => $sections,
]);
}
Models
class Topic extends Model
{
public function categories()
{
return $this->hasMany(HowtoCategory::class);
}
public function sections()
{
return $this->hasManyThrough(Howto::class, HowtoCategory::class);
}
}
class HowtoCategory extends Model
{
public function sections()
{
return $this->hasMany(Howto::class);
}

First and foremost i'd define the foreignIDS in the relations just to make sure that are working as expected.
class Topic extends Model
{
public function categories()
{
return $this->hasMany(HowtoCategory::class);
}
public function sections()
{
return $this->hasManyThrough(
Howto::class, HowtoCategory::class,
"topic_id", "howto_category_id"
);
}
}
then you can get the Topics by searching the sections like so
use Illuminate\Database\Eloquent\Builder;
$topics = Topic::whereHas("sections", function(Builder $query) {
$query->where("howto.description", "something to search")
})->get();
I have a table on my DB with these columnns:
+-----------------+---------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------------+---------------------+------+-----+---------+----------------+
| id | bigint(20) unsigned | NO | PRI | NULL | auto_increment |
| name | varchar(255) | NO | | NULL | |
| value | varchar(255) | NO | | NULL | |
+-----------------+---------------------+------+-----+---------+----------------+
I would access to value values by name.
For example I have these datas:
+----+------------+------------+
| id | name | value |
+----+------------+------------+
| 1 | start_date | 2020-01-01 |
| 2 | end_date | 2021-01-01 |
+----+------------+------------+
I would to get '2020-01-01' by 'start_date'.
I tried this code, but I'm not satisfyed because with this code I get all values of the row, not only the value expected.
Configuration::get()->keyBy('start_date');
I'm not sure I was clear.
Let me know.
Thanks a lot!!
Assuming you want to get an array of key/value pairs, and each key in the name column is unique, you can simply use pluck() (https://laravel.com/docs/8.x/collections#method-pluck):
$configuration = Configuration::pluck('value', 'name');
dd($configuration);
// ['start_date' => '2020-01-01', 'end_date' => '2021-01-01']
Then, you'd use simply array access to use these configuration settings where applicable:
$startDate = $configuration['start_date']; // '2020-01-01'
$endDate = $configuration['end_date']; // '2021-01-01'

How to save time.Now() in mysql table, column name as created_at timestamp null.
I am getting error :
Error:Error 1292: Incorrect datetime value: '2017-08-05 19:06:14.190 +0000' for column 'created_at' at row 1
More Information as asked :- ( I am using fragmenta cms, so all reference code with their line number is given below )

Code that is running it to save :-
At line no. 62 here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/pages/actions/setup.go#L62 )
It calls code
user := users.New()
in Line no. 51 at file here ( https://github.com/fragmenta/fragmenta-cms/blob/master/src/users/query.go#L51 )
New() function is setup.
Which is like :-
func New() *User {
user := &User{}
user.CreatedAt = time.Now()
user.UpdatedAt = time.Now()
user.TableName = TableName
user.KeyName = KeyName
user.Status = status.Draft
return user
}
and their connecting / mysql opening pattern is located here ( https://github.com/fragmenta/query/blob/master/adapters/database_mysql.go#L23 ) .
There is a bug in https://github.com/fragmenta/query. The TimeString method in query/adapters/database.go is not valid for all DBMS adapters.
// TimeString - given a time, return the standard string representation
func (db *Adapter) TimeString(t time.Time) string {
return t.Format("2006-01-02 15:04:05.000 -0700")
}
It's not valid for a MySQL timestamp: MySQL 5.7 Reference Manual, 11.3.1 The DATE, DATETIME, and TIMESTAMP Types. The MySQL TimeString method in query/adapters/database_mysql.go should be:
// TimeString - given a time, return the MySQL standard string representation
func (db *MysqlAdapter) TimeString(t time.Time) string {
return t.Format("2006-01-02 15:04:05.999999")
}
You are trying to insert it using a string query.go:36:
now := query.TimeString(time.Now().UTC())
that is generated by the package that you are using database.go:59:
return t.Format("2006-01-02 15:04:05.000 -0700")
MySQL expects it to be in the pattern of yyyy-MM-dd hh:mm:ss, use the following snippet to apply the pattern to you current Time.time object:
now := time.Now().UTC().Format("2006-01-02 03:04:05")
Anyway, why not to use the SQL function NOW() when inserting the record ?
I have three tables:
- Venue
- Space (belongs to Venue)
- Included Space (belongs to Space)
I receive the id of a Venue in the route and return all the related spaces that I know have Included Spaces(a field called num_included_spaces__c on the Space record that maintains a count of its children). Now that I have all the related parent Spaces for that Venue, I need to find all of the Included Spaces for them.
An Included Space is still a Space, it just happens to have a parent that resides in the same table. I'm trying to turn this:
Venue = Rockdog
- Space = Upstairs
- Space = Media Room
- Space = Courtyard
- Space = Downstairs
- Space = Front Patio
- Space = Indoor Bar
Into this:
Venue = Rockdog
- Space = Upstairs
-- Included Space = Media Room
-- Included Space = Courtyard
- Space = Downstairs
-- Included Space = Front Patio
-- Included Space = Indoor Bar
The Included Spaces table has belongs_to__c and space__c as fields, where belongs_to__c is the id of the parent space and space__c is the id of the child. So i'm looking to find all the Included Spaces where belongs_to_c matches the id of any #spaces returned below
#sub_spaces = Space.where("venue__c = ? AND num_included_spaces__c = ?", params[:venue],0)
#spaces = Space.where("venue__c = ? AND num_included_spaces__c > ?", params[:venue],0)
How would I write this Active Record Query for #included_spaces?
my database schema.

Below function will somehow give you the result you need (in console ofcourse ) however it's not a good solution - it queries database more than needed. However it is the easy -))
def foo id
v = Venue.find(id)
puts v.name
v.spaces.each do |space|
puts space.name
space.included_spaces.each do |spis|
puts spis.name
end
end
end
You can also try a more complex query sth like,
mysql> SELECT spaces.name, included_spaces.name FROM `spaces` INNER JOIN `venues` ON `venues`.`id` = `spaces`.`venue_id` INNER JOIN `included_spaces` ON `included_spaces`.`space_id` = `spaces`.`id` WHERE `spaces`.`venue_id` = 1
-> ;
+------------+-----------+
| name | name |
+------------+-----------+
| Upstairs, | Front |
| Upstairs, | Patio, |
| Upstairs, | Indoor |
| Upstairs, | Bar |
| Downstairs | Media |
| Downstairs | Room, |
| Downstairs | Courtyard |
+------------+-----------+
7 rows in set (0,00 sec)
which should be translated to active record as
Space.joins(:venue)
.joins(:included_spaces)
.where(venue_id: 1)
.select('spaces.name, included_spaces.name')
I have got a table with name table_listnames whose structure is given below

| name | varchar(255) | NO | | NULL | |
+-------+--------------+------+-----+---------+----------------+
2 rows in set (0.04 sec)
It has got sample data as shown
mysql> select * from table_listnames;
+----+------------+
| id | name |
+----+------------+
| 6 | WWW |
| 7 | WWWwww |
| 8 | WWWwwws |
| 9 | WWWwwwsSSS |
| 10 | asdsda |
+----+------------+
5 rows in set (0.00 sec)
I have a requirement where if name not found under the table , i need to insert or else do nothing
I am achieving it this way
String sql = "INSERT INTO table_listnames (name) SELECT name FROM (SELECT ?) AS tmp WHERE NOT EXISTS (SELECT name FROM table_listnames WHERE name = ?) LIMIT 1";
pst = dbConnection.prepareStatement(sql);
pst.setString(1, salesName);
pst.setString(2, salesName);
pst.executeUpdate();
Is it possible to know the id of the record of the given name in this case
