QUESTION
I'm trying to make a relation between my Book entity and a list of languages that I retrieve through a service. In my database, each book has a: ID, TITLE, CATEGORY_ID (FK), LANG_ID

...ANSWER
Answered 2021-Jun-15 at 12:54First of all, did you consider to store language in your database? I mean language are mostly the same, doesn't change too often, you can also store in a properties file and read them at runtime to use them later.
Anyway, I think you should:
- first get from external system languages
- store in variable / in memory cache ( like a Map where you can store id and name )
- read your data from database
- for each row you do
- read book language id, read the cache, get out data you need
- for each row you do
If you can't change model, just use a dto with your entity and the language and you're fine

QUESTION
This is my models to store availability of particular time when a new booking there
...ANSWER
Answered 2021-Jun-15 at 07:03I assume the problem is that start_hour
and end_hour
that fall within an already existing time range are allowed to be added. Of course the unique_together
constraint cannot handle this as it only deals with uniqueness not uniqueness in a range. Instead you can override your models clean
method and perform this validation there:
QUESTION
Thank you in advance for any help provided as it's much appreciated! Hope you're all keeping well in these uncertain times.
I have a question regarding Google Sheets. Below you'll find a link to a very large Google Sheets document in which I am trying to substitute text such as 'XXXXX', 'BBBBB', 'TTTTT', 'YYYYY', 'RRRRR' and replacing the same phrases into situations later in the document. If someone could help input a formula into columns such as P, Q, R, S, T, V and W that would be really helpful. I believe I have made the document pretty self-explanatory where in row 1 you can find the labels 'XXXXX', 'BBBBB', 'TTTTT', 'YYYYY', 'RRRRR' and the places to replace them respectively in columns P, Q, R, S, T, V and W.
I have tried to use an arrayformula with substitute, but every time I did this I could only change the first row and it would not cascade down the sheet to affect the other 900+ rows no matter what I tried.
I would appreciate an explanation of how to do it if someone is changing the document so I can learn moving forwards!
The other thing which I am very confused about how to achieve is, if in column O the word 'Yes' appears, then I would like 'VF' to come into column W but if it says 'No' in column O then I don't want it to appear in column W.
Again an explanation of how this is achieved, as well as implementing it into my document would be much appreciated!
Thank you.

...ANSWER
Answered 2021-Jun-14 at 18:55You can use Arrayformula
and combine the text using &
.
For example in the cell P4 you can have the formula:
=ArrayFormula("How can I buy "&F4:F&" at a trade price? In order to enquire about purchasing "&F4:F&" at a trade price, please get in touch with us at sales@drinksshop.co.uk")
So you are basically just adding text to F4:F
using &
. You can do this to all the other columns accordingly.
And using the same logic you can add the following formula in cell W4:
=ArrayFormula(F4:F&", "&J4:J&", "&M4:M&", "&IF(O4:O="Yes", "VF", ""))
