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...

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:
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.

You can use

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:...
ANSWERAnswered 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] )
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):...

Add a second HierarchyGrant to restrict its visibility, such as:
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)...

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.
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:...
ANSWERAnswered 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.
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
ANSWERAnswered 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. 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....
ANSWERAnswered 2020-Jun-15 at 14:05
As there's only a limited supply of colors, and each line should have it's own, the modulo operator seems fitting:

instead of using request.data try

Good morning, I have a question I try to pass some parameters to an sql query of the pentaho cde and I get an error (the query does not show anything). The examples that I look on the internet use MDX on Mondrian. Is it mandatory to create a schema in Mondrian and use MDX? Thank you very much...
ANSWERAnswered 2018-Sep-10 at 09:39
You will find below description from pentaho docs
- To create a new Mondrian schema, click the New button, or go to the File menu, then select New, then Schema. A new schema sub-window will appear. Resize it to fit your preference.
- It's easier to visualize your physical data model if you have it in front of you. Turn on the JDBC Explorer from the New section of the File menu and position it according to your preference. If you have a third-party database visualization tool that you are more familiar with, use that instead. The JDBC Explorer is not interactive; it only shows the table structure of your data source so that you can see at a glance what the names of the columns and rows in it.
Typically your first action when creating a schema is to add a cube. Right-click the Schema icon in the schema window, then select Add cube from the context menu. Alternatively you can click the New Cube button in the toolbar. A new default cube will show up in your schema.
Add a table by clicking the New Table button, or by right-clicking your cube, then selecting Add Table. This will be your fact table. Alternatively you can select View or Inline Table if these are the data types you need for your fact table.
- Click the Table entry in the name field of your new table, and select or type in the name of the table in your physical model that you want to use for this cube's fact table.
- Add a dimension by right-clicking the cube, then selecting Add Dimension, or by clicking the New Dimension button.
- When you add a dimension, a new hierarchy is automatically created for it. To configure the hierarchy, expand the dimension by clicking the lever icon on the left side of the dimension's tree entry, then click on New Hierarchy 0. Choose a primaryKey or primaryKey Table.
- Add a table to the hierarchy by right-clicking the hierarchy, then selecting Add Table from the context menu.
- Add a level to the hierarchy by right-clicking the hierarchy, then selecting Add Level from the context menu.
- Add a member property to the level by right-clicking the level, then selecting Add Property from the context menu.
Add a measure to the cube by right-clicking the cube and selecting Add Measure from the context menu.
Choose a column that you want to provide values for, then select an aggregator to determine how the values should be calculated.
These instructions have shown you how to use Schema Workbench's interface to add and configure basic Mondrian schema elements.
