Same issue I posted Friday but I will be more specific this time. I have this data:
UserId Action Id Date
1 1 1/1/2018
1 2 1/1/2018
1 2 2/1/2018
2 3 3/1/2018
2 4 4/1/2018
And I want a filter that will yield the following:
Count Instances from FirstDate to 2/1/2018
UserId ActionCount
1 3
2 0
In the data load editor you want to group by the User in order to get that first date:
GroupedUserData:
Load
UserId
min(Date) as FirstDate
resident [The name of your original table];
And then you want to use set analysis chart-side:
sum({<FirstDate = {'<=2/1/2018'}>} ActionCount)

verion and id are composite key . i want to add auto increment secondId . for all id , secondId is same but version is diffrent. i dont konw how to handle this in code first EF .
i write blow code in dbcontext file
modelBuilder.Entity<user>().HasKey(e => new { e.Id, e.Version });
modelBuilder.Entity<user>().HasAlternateKey(q => new { q.Version, q.SecondId });
modelBuilder.Entity<user>().Property(q => q.SecondId).UseIdentityAlwaysColumn();
modelBuilder.Entity<user>().Property(q => q.SecondId).HasIdentityOptions(1000);

With the following query i get count of click on all social anchors per day, but i want to show in the chart also which social anchor has been clicked on that day.
$social_stats= Social::join('social_statistics', 'social_statistics.social_id','socials.id')
->select( array(
'social_statistics.visited_at as visited_at',
DB::raw('count(*) as count'),
)
)
->orderBy('visited_at')
->groupBy('visited_at')
->pluck('count','visited_at')
->all();
Need to render a Chart that shows by day the count of click on different social.
$social_bar_chart = new SocialBarChart;
$visited_at = collect(array_keys($this->social_bar));
$social_bar_labels = $visited_at->map(function ($date) {
return Carbon::parse($date)->format('d/m');
})->toArray();
$social_bar_chart->labels($social_bar_labels)
->dataset('Social Count', 'bar', array_values($this->social_bar))
->options([
'tooltip' =>['show' => true],
'backgroundColor' => '#54a0ff',
]);
I have a situation where each Order can have Feedback. In case the product is physical, the Feedback can have many packaging_feedbacks. The packaging_feedbacks are supposed to be a relation to the packaging_feedback_details.
Feedback Model
public function packagingFeedbacks()
{
return $this->hasManyThrough('App\PackagingFeedbackDetail', 'App\PackagingFeedback',
'feedback_id', 'id', 'id', 'user_selection');
}
packaging_feedback_details
id|type_id(used to group the "names" for each feedback option)|name
1 0 well packed
2 0 bad packaging
3 1 fast shipping
4 1 express delivery
packaging_feedbacks
id|feedback_id|user_selection (pointing to the ID of packaging_feedback_details)
1 1 2
2 1 6
3 1 7
4 1 12
5 1 15
6 1 17
7 2 1
8 2 6
9 2 7
10 2 12
11 2 15
12 2 17
13 3 1
14 3 6
15 3 7
16 3 12
17 3 15
18 3 17
Now I would like to be able to get the average selection of the users for a physical product. I started by using:
$result = Product::with('userFeedbacks.packagingFeedbacks')->where('id', 1)->first();
$collection = collect();
foreach ($result->userFeedbacks as $key) {
foreach ($key->packagingFeedbacks as $skey) {
$collection->push($skey);
}
}
foreach ($collection->groupBy('type_id') as $key) {
echo($key->average('type_id'));
}
But it returns not the average id since it will calculate the average not the way I need it to calculate. Is there some better way, because I think it's not the cleverest way to do so. Is my database design, in general, the "best" way to handle this?
The type of average you're looking for here is mode. Laravel's collection instances have a mode() method which was introduced in 5.2 which when provide a key returns an array containing the highest occurring value for that key.
If I have understood your question correctly this should give you what you're after:
$result->userFeedbacks
->flatMap->packagingFeedbacks
->groupBy('type_id')
->map->mode('id');
The above is taking advantage of flatMap() and higher order messages() on collections.
My dataset consists of a number of variables:
* Example generated by -dataex-. To install: ssc install dataex
clear
input float(v1 v2) str11 Date float(v4 v5 v6 v7 v8)
1 2 "15-aug-2016" 1 1 1 1 1
1 2 "07-may-2015" 1 1 1 1 50
1 2 "07-may-2015" 1 1 1 1 88
1 2 "15-aug-2016" 1 1 1 1 29
end
The variable date is a date and time and is formatted as a datetime
generate double date = date(Date,"DMY")
My duplicates are the same for v1-v2-v4-v5-v6-v7 (as in the example), while v8 is different.
I need to delete duplicates based on v1-v2-v4-v5-v6-v7 and keep the one with the smallest date (here 07-may-2015).
I have tried without success:
1.
gsort -date
bysort v1 v2 v4 v5 v6 v7: generate dublet=_n
order dublet date
keep if dublet==1
drop dublet
--> Works for the first 25 rows or so, then keeps the wrong one a couple of times and then the right one again. (Seems to me, that the bysort command removes the sort done by gsort? Any knowing if that's correct?)
bysort v1 v2 v4 v5 v6 v7 (date) : keep if _n == _N
--> Obviously keeps the wrong one, since Date is not -Date.
However, -Date is not an option - Stata writes: - invalid name
You could change your second answer to bysort v1 v2 v4 v5 v6 v7 (date) : keep if _n == 1 and that should give you what you're looking for.
Since in your data example there are duplicate dates (2 observations are May 7th 2015) you will get a random one of the observations with the minimum date.
Hi I have two tables in DB.The first table is given below.
Table name-
t_hcsy_details
class name in model-
class THcsyDetails < ActiveRecord::Base
end
The values in side table is given below.
HCSY_Details_ID HCSY_ID HCSY_Fund_Type_ID Amount
1 2 1 1125
2 2 2 390
3 2 3 285
4 2 4 100
5 2 5 60
6 2 6 40
My second table is given below.
Table Name:
t_hcsy_fund_type_master
class in model:
class THcsyFundTypeMaster < ActiveRecord::Base
end
Table values are given below.
HCSY_Fund_Type_ID Fund_Type_Code Fund_Type_Name Amount
1 1 woods 1125
2 2 Burning 390
3 3 goods 285
4 4 brahmin 100
5 5 swd 60
6 6 Photo 40
I know only HCSY_ID value(i.e-2) of first table.But i need Fund_Type_Name and Amount from second table.As you can see one HCSY_ID has 6 different records.But i need all Fund_Type_Name and Amount of one HCSY_ID. Please help me to resolve this issue by creating object for both two classes shown above.Please help me.
You haven't specified any relationships setup, so it would be easier to split this in two queries:
# you already have hcsy_id
fund_type_ids = THcsyDetails.where(hcsy_id: hcsy_id).pluck(:hcsy_fund_type_id)
fund_types = THcsyFundTypeMaster.where(id: fund_type_ids)
fund_types.group(:fund_type_name).sum(:amount)
In case you had proper relationships setup, the above would've simplified to:
THcsyDetails.
joins(association_name). # THcsyFundTypeMaster
where(hcsy_id: hcsy_id).
group("#{t = THcsyFundTypeMaster.table_name}.fund_type_name").
sum("#{t}.amount")
