How to load data from a CSV file in D3 v5
(2 answers)
Closed 2 years ago.
I am trying to load a csv file using below code.
Method 1:
d3.csv("data/aaa.csv", function(error, data) {
console.log(data[1]);
})
The console shows undefined instead of the data row. Nonetheless, this is the most common method you can find on all forums.
However, if I use below method 2 loading the data, it correctly shows the data row.
Method 2:
d3.csv("data/aaa.csv").then(function(data) {
console.log(data[1]);
});
I am a bit confused why this is happening.

I'm using Go HTML templates and when you run this function it sends the data to the client, but I would like to store that data in a variable and send it to the client later. How can this be achieved?
func (t *Template) ExecuteTemplate(wr io.Writer, name string, data any) error
This is for use in an AJAX response. I know on the client side I could simply parse the xhr.responseText, but I need to send some other variables with it.
Use a buffer:
buf:=bytes.Buffer{}
t.ExecuteTemplate(&buf,"name",data)
Then you can use buf.Bytes(), or buf.String().

I am using EMQX Kuiper.
https://docs.emqx.io/en/kuiper/latest/rules/overview.html#sinks-actions
Where in my rule settings, I am using dataTemplate property to fetch my data. Where I have to use Go template. No way to write go script only template.
Using this template I able to print first item of my slice.
"dataTemplate": "{{json (index . 0)}}"
But I need to print last item of my slice. Can't print this.
Tried to achieve that with the Go template language like this,
"dataTemplate": "{{$lenMyList := len .}} {{json (index . $lenMyList -1)}}"
But to no avail.

Discord.py ctx.guild.edit works but not self.bot.guild.edit?
(1 answer)
Closed 2 years ago.
How can I change the server name? I'm trying that code but I get an error( TypeError: edit() takes 1 positional argument but 4 were given)
await ctx.guild.edit(ctx.guild.name, None, "New name")
Can you please help me?
Due to the API Reference your second parameter is not necessary, because the default value for reason is already none.
Try either
await ctx.guild.edit("New name")
or try to append your value to the needed keys in the dict **fields, like:
await ctx.guild.edit(name="New name")
and other parameters from the available one if necessary.
