QUESTION
I read this answer, which clarified a lot of things, but I'm still confused about how I should go about designing my primary key.
First off I want to clarify the idea of WCUs. I get that WCU is the write capacity of max 1kb per second. Does it mean that if writing a piece of data takes 0.25 seconds, I would need 4 of those to be billed 1 WCU? Or each time I write something it consumes 1 WCU, but I could also write X times within 1 second and still be billed 1 WCU?
Usage
I want to create a table that stores the form data for a set of gyms (95% will be waivers, the rest will be incidents reports). Most of the time, each forms will be accessed directly via its unique ID. I also want to query the forms by date, form, userId, etc..
We can assume an average of 50k forms per gym
Options
First option is straight forward: having the formId be the partition key. What I don't like about this option is that scan operations will always filter out 90% of the data (i.e. the forms from other gyms), which isn't good for RCUs.
Second option is that I would make the gymId the partition key, and add a sort key for the date, formId, userId. To implement this option I would need to know more about the implications of having 50k records on one partition key.
Third option is to have one table per gyms and have the formId as partition key. This seems to be like the best option for now, but I don't really like the idea of having a a large number of tables doing the same thing in my account.
Is there another option? Which one of the three is better?
Edit: I'm assuming another option would be SimpleDB?

I am already making a restful API using nodejs on the backend, here is my folder structure :
...ANSWER
Answered 2021-Jun-10 at 18:26- Why it works on Postman and not on the client code?
The difference is the format of the request. In Postman, you're sending the data as JSON object. While in the client code, you're sending data inside a form-data. They are different. That's why the req.body
is empty. Different request formats require the server to parse in different ways.
I see in your code the line //formData.append("thumbnail", newProject.thumbnail);
is commented, you prepare to send the project's thumbnail in the request. In this case, you cannot send the request in JSON format. You need to modify the server to make it understand the form data.
For this, I recommend this popular package
Multer is a node.js middleware for handling multipart/form-data, which is primarily used for uploading files.
QUESTION
i tried to follow this mysql - move rows from one table to another with action to perform a "move to archive" function using PDO and i am failing miserably.
So i have created a job card system, and to cut it short, when a job is complete, i have a "ARCHIVE" button that essentially needs to move the selected job card from table "repairs" into table "archived_repairs". The 2 tables are exactly the same, it just needs to be deleted from repairs table and moved to archived_repairs table in case we need to come back to it at a later stage.
This is the button/link i am using on my CRUD table:

While replicating:
https://sortablejs.github.io/Vue.Draggable/#/nested-example

I ran into an issue related to the model; how can I add draggable to vue components instead of a raw json (as used in the example).
What I want to do is, add drag and drop to:
https://codesandbox.io/s/gg1en
(each item can be moved ("dragged") from one group to another, each group can be dragged from a lower position to an upper one (and vice-versa).

...ANSWER
Answered 2021-Jun-14 at 09:44If you have a component prop that's being mutated, there are multiple options:
- Convert your prop to a custom v-model. It will allow two-ways bindings without problems. (Use the prop name
value
and sent$emit('input', this.value)
to update it. - Use
prop.sync
modifier, which is kinda the same as usingv-model
but the prop has a specific name. Use:data.sync="myItems"
on the parent, and run$emit('update:data', this.data)
inside the component to update it. - Copy the prop to a data variable inside the component. So that the prop is only used as a default value for this data, but then it's only the data that's being mutated. But this won't allow the parent to see any modifications on that prop since it's not being updated directly.
QUESTION
I am trying to write some basic CRUD operations using JDBC. I'm wondering if there is a way I can use the same prepared statements for multiple tables. Right now, I have a function for every table, and it seems redundant, but I'm unsure how I can make it better.
Some code examples:
...ANSWER
Answered 2021-Jun-14 at 00:48You can't make a single prepared statement that inserts into different tables depending on some parameter.
Identifiers (for instance, table names) must be fixed at the time you prepare the statement. During the prepare, the SQL engine checks your syntax and also checks that the table exists. Once that validation is done, you can use the prepared statement freely and those checks don't need to be done as you execute. If you could change the table name per execution, then the SQL engine would need to re-check every time, which would partially defeat the purpose of preparing the statement.
Once the statement has been prepared, you can only change values. In other words, parameters can be used in place where you would have used a quoted string literal or a numeric literal, but no other part of the query.
