Hi dude,

I think you did wrong by truncating then html. Besides, when you use
‘:omission’ option, the computed length take in consideration the length
of
‘…(continued)’. The best way to do this would be to create a helper
method like truncate_text

truncate_text(text, length, end_text)
end_text ||= ‘’ # end_text as an optional parameter
new_text = truncate(text, :length => length)
new_text = new_text + end_text
new_textend

And then use it in you r html like this:

some_text = “TruncateHtml is just like the vanilla truncate rails
helper , TruncateHtml is just like the vanilla truncate rails helper”

Good luck

Lionel

Hi dude,

Good Day,

My some_text content like this = “

TruncateHtml is just like the
vanilla truncate rails helper , TruncateHtml is just
like
the vanilla truncate rails helper

”

As you said i pasted helper code in my pp_helper.rd and in my view,

app_helper.rb
def
truncate_text(text, length, end_text) end_text ||= ‘’ # end_text as an
optional parameter new_text = truncate(text, :length => length) new_text

new_text + end_text new_text end

my_view

  • some_text = raw a.content
    = truncate_text(some_text, 15)

I got an error

wrong number of arguments (2 for 3)

Extracted source (around line #147):

144: = raw a.name
145: .ra
146: - some_text = a.content
147: = truncate_text(some_text, 15)
148: .con12
149: = “read more…”
150: .alert_msg

Please advice.

How many arguments has this method got?

end_text ||= ‘’ # end_text as an optional parameter new_text = truncate(text,
:length => length) new_text = new_text + end_text new_text end

my_view

  • some_text = raw a.content
    = truncate_text(some_text, 15)

How many arguments are you passing?

I got an error

wrong number of arguments (2 for 3)

I wonder what that means. The clue may be in the error message.
