How do you setup a definition to have default null value?

System Information

Strapi Version: 3.6.2 Operating System: Ubuntu 20.04.2 LTS Database: mongo db “version”: “4.4.6” Node Version: v14.17.0 NPM Version: 6.14.13 Yarn Version: 1.22.5

Hi, I’m currently using an old version of strapi v3.0.0-alpha.23 and upgrading to the latest v3.6.2 release. However, I noticed that in the latest release, strapi is removing the default: “” from all the models when you add or update content type models. My issue is similar to this issue and I noticed it …

Allow definition of null as default value

How can I set "default value" to blank?

I need set some string field’s defalut value to “”, but I can’t set it via admin tool. So I add "default": "" line to model.setting.json manually like this: "name": { "type": "string", "default": "" }, But if I edit model.setting.json(such as add a new field, or adjust some field setting). then the "default": "" was removed from model.setting.json. My question is can I keep "default": "" in setting.json file?

System Information

Strapi Version: 3.6.2 Operating System: macOS Big Sur Data…

From what I am reading here the default value should be sent to 0 in this case, and can’t be sent as null. Is this correct? Or is there a way to pass null?

Thanks!

The default value for in the database is always null, if you set default value in admin panel

[commentsBot]

It will be handled by admin panel only

[commentsBot]

So if you don’t set some value doing POST request I will be null

[commentsBot]

Or throw validation error

[commentsBot]

So the post request currently has this following logic when creating the request to send:

seamHeight: ss_test?.seamHeight ?? null

I am unsure how to not set some value when sending this POST request. Do you have any suggestions?

Just use undefined

[commentsBot]

But that’s legit

[commentsBot]

It’s going to be null

[commentsBot]

Unless it set mandatory

[commentsBot]

Let me try it real fast and see if it’ll go with undefined

[commentsBot]

Then it will throw error

[commentsBot]

If it throws then the proper solution is to remove validation in admin

[commentsBot]

Hmm, looks like using undefined got me a new error instead.

*These fields are not set to mandatory

Update

You can POST a null value into a content-type field that has type of Number. There are no issues with this.

The reason I was seeing this error was because the field seamHeight was set to type: “integer” and there was an instance of one of the values I was passing in being a decimal.

As for the other error I saw referenced in my comment above this it was because I broke my Strapi Admin panel and needed to restart it before doing the POST request.

The error obviously pointed me in the wrong direction, and maybe that’s worth looking into, but I got it working with just updating the content-type field seamHeight to type: “decimal”.

Red herring errors are annoying but glad you’ve got it sorted.
I was going to chip in and confirm you can, but it’s always good to peer code through these kinds of things.
Happy you got there in the end!
