QUESTION
Good day. Tell me how can I iterate over an array taking values for filters from an object?
...ANSWER
Answered 2021-Jul-18 at 06:41You can use Object#entries to get the pairs of the filter object.
Then, using Array#filter, iterate over the array and return the matching elements using Array#every:
QUESTION
I need to make list of products that will filter on click. But i just can't get a grasp on how to do it in react. And mainly:
- where to make filtering function?
- How combine and pass the data to reducer?
- How to trigger it all with 1 button.
I'm sure it's very trivial case for an experienced devs.
repository with my code so far: https://github.com/SolidMike/react-hotels/tree/main/src/
As for now i have component that outputs my json and component which contain all filters. I sadly just can't understand how to make it work with my actions and reducers :(
This is my Filter
...ANSWER
Answered 2021-Mar-13 at 13:35One of the patterns that I extensively use, and not only with redux, is keeping lists in two state variables. First one is hash map of all entities mapped by some identifier, and another one is list of identifiers. For example, you have list of hotels. I would do it like this:

I'm trying to figure out how to remove duplicates based on the url, as the aggregate query can match the same document twice if say "APPL" and "TSLA" are in stocks and included in the same document.
ANSWER
Answered 2021-Jan-16 at 06:11You can use $group stage after $match stage,
$groupbyurland get first root document using$$ROOT, this will return document inrootfield
QUESTION
everyone!
Following the "Pentaho Analizer Cookbook" PDF, I tried to stablish a level-based measure.
My cube has a single dimension hierarchy: Clients that have Projects that have Buildings that have Phases that have Costlines level 0 that have Costlines level 1.
So, there let be samples for both fact and dimensions:
...ANSWER
Answered 2020-Nov-18 at 11:00As the Pentaho Analizer Cookbook specifies, that Formula is for pinning a Measure to a certain level.
It is: if you drill-down, you'll get the value as the drill-up.
If what you need (if I understood correctly) is to just display nothing for upper-levels, then user the next Formula:
IIF([Dimensions].CurrentMember.Level.Ordinal < 3 , NULL , [Measures].[My measure] )
QUESTION
I have a DB with different clients (table TD_CLIENTS), which shall have access to a mondrian Cube. Obviously, I want each client to be able to see only data of its own.
I've accomplished this with a role per client (I have few clients, so this is an acceptable trade-off. Anyway, if anyone knows of a better way, I'll be SO happy to hear it):

QUESTION
Word of notice: I'm a total novice regarding Mondrian, and I'm struggling so hard to make a cube with a multi-level hierarchy.
These are my tables (Postgresql, but should work on any other DBMS)
...ANSWER
Answered 2020-Nov-11 at 22:41If anyone stumble with this question, then, you're likely making the same mistake as I am:
After quite some hours comparing other folks' Mondrian schemas with mine, and having a look at the book "Mondrian in action", I realized I was making a total misuse of the parentColumn, which is (I think) aimed to point to the same hierarchy level, such as in employees with supervisors that are also employees.
The solution is to completely remove parentColumn property of the xml.
QUESTION
I feel like I am missing something: I have simple MDX query and rather simple Mondrian code, yet, it still behaves weirdly - that is the results of the query differ depending on whether XML schema contains unrelated to query dimension(s).
At this point I am using this code:
...ANSWER
Answered 2020-Aug-11 at 16:15The test MDX query does not specify the slicer (WHERE clause). In this case the slicer is created automatically and includes all dimensions which are not mentioned on other axis. Moreover slicer is built with default dimension elements. As you have not specified any default members when defining dimension, Mondrian just takes the "first" element. What is the first element can be determined by the dimension ordinal (or sorting of the dimension elements). So I guess Mondrian just gets the "null" element as the first element in the dimension. I would suggest to adjust your Mondrian schema so that each dimension has a default order and perhaps add some filters to exclude NULL element values.
QUESTION
I can not understand documents about Pygments Styles, which says:
To make the style usable for Pygments, you must
- either register it as a plugin (see the plugin docs)
- or ... put it into the file mondrian.py and this file into the pygments.styles subpackage directory.
Now there is already a Dracula theme for Pygments, how can I add it as a new pygments style, so that I can use the style by a simple command line (E.g. pygmentize -g xx.py).
Either by registering a plugin, or puting dracula.py in to the pygements.styles subpackage directory (where it is?). I just don't know how to do this, and there is not a single example.
PS: My OS is ubuntu-18.04 and I install pygments by sudo apt-get install python-pygments python3-pygments
ANSWER
Answered 2020-Jul-12 at 19:23For me (also Ubuntu 18.04), the path of the installation directory is: /usr/lib/python3/dist-packages/pygments. There you will find another directory named styles where all the existing color themes are present (e.g. autumn.py, fruity.py). You may create your own style (following: https://pygments.org/docs/styles/) and store the corresponding style file here.
I hope this partially answers your query.

I'm trying to make my own Java GUI project. I want to make the line's colors change when mouse pressed, but this doesn't work. I used 'for'loop and array for Colors but this doesn't run. So I'd like to ask you help me to solve it! Also, I wonder why loop needs for drawing lines on panel.
...ANSWER
Answered 2020-Jun-15 at 14:05As there's only a limited supply of colors, and each line should have it's own, the modulo operator seems fitting:
