gohtml | HTML formatter for Go | Code Quality library

I got success to write code to submit html form data as single excel row. But in my html form I want to submit multiple data which should be appended in single cell of excel but second part of data should start with new line in the same cell. Just like (ALT + Enter Operation). My html code is as below.

index.html

I have written some Golang code which works when tested on my local machine. When I deploy this as a Google Cloud function it fails because it cannot open a template file. The line of code failing is:

I am self-teaching myself go and I have started experimenting with using go as a back end.

I have the following code which renders HTML pages, but I am looking for a solution that doesn't rely on a third party import to get a better grasp of what is going on and what needs to be done.

I have a simple form which I want to bind on the post request.

Here is the form:

I'm trying to learn Golang. I want to do simply sending data to view. But data is does not reaching to main.gohtml. I could not understand the reason. If I print the data out of the define it works. But If I want to print data in the define "content" (goes to main.gohtml), data is coming empty.

define "title" part is working. Just I cant send data with variable. If I delete {{.text}} part and write something, it works.

main.go file

coders. I need to render the nested struct data in go template. I wonder if it possible to do with nested loops in .gohtml template file. Here is my .gohtml code:

I have a struct A with a slice B of struct C and other datatype. I am passing it to the gohtml template. How can I access the elements of struct C in gohtml template.

I have a Golang function to fetch all the records from Postgres database, this function is simply using :

SELECT * from stock_transactions I want to apply filter to this function to fetch records with some conditions, in-short I want to use :

SELECT * from stock_transactions WHERE symbol = $symb

The problem is to handle the case where if $symb = null the query should act as SELECT * from stock_transactions. I can write an if-else clause for the same but if the number of parameters are more than 2 it could be messy. Is there a better way to handle this?

My function:

I have such where I send to template years data (which is slice of structs). How can I access on template side AcaYear field of only 2nd item (struct)? Whole second item I can access as {{index . 1 }}. I also can range over slice and get AcaYear fields of both all items. But need only AcaYear field of second item (result should be 2021-2022).
