In the laravel project I'm currently working on I want to store watchlists of contents for each user.
I'm wondering now what is the best way to do it, I came up with adding a column to the users table named watchlist and then store a json string in there containing all contents on the watchlist of that user.
But I feel like this is the most simple and basic way to do it. Is there any better/ more elegant way to do it? FYI: I use mysql.
if the list items comes from another columns, i prefer to put the user watchlist in table instead of putting in on a json, because of cascading or any future update.

I have a database containing many records - let's say its a people database and the columns contain Name, Surname, Age, FreeText.
I want that this data to be displayed in a list on my website. Each item in the list should contain the database' row data.
In detail, each list item should be a custom HTML div consisting e.g. of 2 columns, where in the first column the Surname and the Name should be displayed in the first row, the age in the second. In the second column there should be the free text.
There should also be a onClick listener on this item.
I am a Wordpress Beginner, I have no idea how to achieve this. I think the general approach has to be: Get records from DB, create the items dynamically, put the into the list, and display the list on the page.
I purchased the Avada theme for the design, but this kind of functionality does not seem to be included.
Any hints where to start? Do I have to create dynamic php files, and if yes, how? With javascript? Or are there Plugins available which I can use?
i find this plugin for you try this link:
https://wordpress.org/plugins/participants-database/
This plugin offers all the functionality needed to build and maintain a database of people or anything you want. The database is fully configurable, allowing you to define all the fields of information you want to store for each record. The records can be entered individually in the WordPress admin section, imported with a CSV file, or let the individuals themselves create their own record. Display lists of records can be sorted and filtered by any field, and the result exported as a CSV file.
What is the best way to organize a big database.
The way it works is that only I am allowed to touch or modify the database but interns help sometimes to collect data, we used to have the whole system excel based, back than we had the macro which by choosing 2 files it will integrate and mark in colors the changes.
How can I create something friendly to use which will update by pressing a button and also will show changes!! I am familiar with the update query, however:
it doesn’t track any changes.
I want to know other options.
To sum up the way of processing is:
I have the database and I need to split some data to smaller files so other employees will work on.
Then I will collect the files and integrate with the existing database, but since we are all human mistakes can happened that’s why I want to be able to track easily changes.
The updates are going to happen often. When I will give the intern a temp. table The possible changes are for example: address, phone number, price, they will do those researches based on current data which they will find online which information has been changed, and they will change the info which is on the temp. table, That is why I want to be able to know what exactly did they found out. Lets say if Product A (product ID1234) used to cost 10$ and today its 12$ from the same supplier. I just want to know and to see that the price for product ID1234 has been changed. Not only to have it updated to the back end database. For quality assurance I need to track which new input they did in relation to the product ID. (some times input by someone else which was done in wrong format or wrong column could affect big time on the quality of the reports)
So this was the explanation for what I need the reports
So in order to make those temp. tables, I want to create a form for it that by choosing region, category etc. and then clicking on a button it will automatically select the relevant records from the database, create a new table/access-file and then copy the selected records to the temp. table. So someone else could work on it...
Next thing is that it would be nice to know how can I create a template for tables, by template I mean to standardize by validation rules. some fields I'd like to have dropbox menu, some fields ready mask for phone number.... etc.
Final part, after they made the changes and saved the file (the temp. table which they were working on), I want to be able to update the back-end database via clicking on a button...
Looking forward to get the best solution!
Thanks in advance J

Okay for the temp tables thing:
why not split your database in a backend part (having all the tables) and a frontend part which contain the forms and tables the interns need? I'm guessing mostly it is going to be the same so you can even create multiple different frontend's to give to different interns incase they need other tables. There are a lot of articles out there about splitting a database and linking tables.
Then the thing about the record changes not sure is this is what your looking for but it could help, i haven't used it myself so not sure what it exacly does. But this may help you a bit.

I would consider taking a look at the BeforeUpdate event for the form. You can trap the old and new values of textboxes if the form is bound to a table. You could loop through all the controls on your form and check for Me.Control <> Me.Control.OldValue. If they don't match, write both values to an auditing table so you can go back and check whenever you want to. I would include the following fields in your auditing table:
ChangeDate
TableName
ControlName
OldValue
NewValue
Then you can query that table any time you want to see what has changed.
I'm starting to learn Talend and I'm facing this problem: I have several ID's as an input and I want to make a lookup for each of these ID's to output the obtain data in a Json output.
Here's an image showing what I want to achieve:
http://i.stack.imgur.com/GLVLf.png
I have a tXMLMap with a lookup to the table where I want to find the villains from the villainID's list. The image shows how I can get the ID and Name for one of the villainID's and output it in it's respective json field but this method only works for one ID lookup at a time.
What's the best way to achieve this?
Thanks!
You should be able to copy your second input table 8 times and link all of those back into the tXMLMap component and link those by key as you already have done and join those up to where it needs to go in the XML mapping.
Alternatively you could use a tMap component in a previous step and use that to generate waveNvillainN's dispName by joining the id of your lookup table to all of the waveNvillainN's ids. This should then leave you with all of the necessary fields to populate the XML mapping.
This is the way I could find out to solve this issue, I think it's the same that #garpitmzn and #ydaetskcoR meant but I'm not sure. This works perfectly and was easy to implement but I'd just hope there was a way to have less clutter of components.

just facing a little problem right now.
I have a layout-table that contains one field pages. This should specify for which pages the layout should be applied.
The possible contents are "closed" ranges like '3-5' or open ranges like '3-*'. But it should also be possible to add single pages.
So is there a good way to accomplish a content like that
'3-5;11;15;17-*'
in a single field?
Or do you know better ways?
Is there a possibility to query this field like
SELECT * WHERE IN_RANGE(pages, '5') (Pseudo-Code)
I want to prevent creating a table page because it would contain nothing else and also don't want to do the validation in php.
I am happy to provide more information if necessary.
This is a tricky question i dont see "native" sql option for this.
My first idea was to store information about pages as varchar and implement method to tokenize that string so youll have values which you can then process by sql query.
Is it possible with LINQ to do a cross tab query to add new columns? These columns come from a second and third table and need to be converted to JSON to be displayed in a Telerik table.
One table contains the name of the columns that need to be displayed and the other contains the value for the rows of each column, and this relates to the first table, which has the main related data.
I have investigated dynamically creating the extra columns, but also come unstuck as they need to go through JSON serialization, as well as the difficulties of creating new properties within any class dynamically.
Any ideas would be helpful.
Regards
Mark
I hope this helps, although I'm not sure I understand completely what you're asking ...
Since you're serializing to JSON anyway (and so presumably are not overly concerned with schema/type info), I would suggest just using a Dictionary and populating your data that way. It sounds like you could run some kind of nested loop, cycling through the column names from the one table, and pulling the values from each column from the second table.
EDIT
BTW, it is possible to do dynamic properties using System.ComponentModel, although this seems like overkill from how you described your scenario (you don't require data binding, for instance). Here's a good post on SO, if you're interested: Data binding dynamic data
