            How to filter array of objects by object in JS
            Asked 2021-Jul-18 at 06:41

            Good day. Tell me how can I iterate over an array taking values for filters from an object?



            Answered 2021-Jul-18 at 06:41

            You 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:



            Apply and reset multiple filters on click with redux
            Asked 2021-Mar-13 at 13:35

            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:

            1. where to make filtering function?
            2. How combine and pass the data to reducer?
            3. 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:

            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 :(

            One 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:



            How to remove duplicates based on property after an aggregate query?
            Asked 2021-Jan-17 at 23:53

            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.



            Answered 2021-Jan-16 at 06:11

            You can use $group stage after $match stage,

            • $group by url and get first root document using $$ROOT, this will return document in root field



            OLAP level-based measure drilldown issue
            Asked 2020-Nov-18 at 11:00


            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:



            Answered 2020-Nov-18 at 11:00

            As 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] )



            mondrian role: filter by hierarchy and hide hierarchy
            Asked 2020-Nov-13 at 13:20

            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):

            mondrian hierarchy error: In the current implementation, parent/child hierarchies must have only one level
            Asked 2020-Nov-11 at 22:41

            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)



            Answered 2020-Nov-11 at 22:41

            If 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.



            Mondrian tries to optimize Segment.load weirdly resulting in partial or fully empty results
            Asked 2020-Aug-11 at 16:15

            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:



            Answered 2020-Aug-11 at 16:15

            The 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.



            How to use Dracula theme as a style in Pygments?
            Asked 2020-Jul-12 at 19:23

            I can not understand documents about Pygments Styles, which says:

            To make the style usable for Pygments, you must

            1. either register it as a plugin (see the plugin docs)
            2. or ... put it into the file 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

            Either by registering a plugin, or puting 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.

            Answered 2020-Jul-12 at 19:23

            For 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., You may create your own style (following: and store the corresponding style file here.

            I hope this partially answers your query.
