I want to use angular-botstrap-ui in my application. But I don't know how I can build pagination.
Let's say I have 100 records in table and I want to fetch 10 results in table row. By using ng-repeat I am getting 100 rows but I want to limit them using pagination. How I can achieve that?
I have solved this in using the array function slice
ng-repeat="row in queryResult.rows.slice(((currentPage-1)*10), ((currentPage)*10))"
I have written a blog post about my ingenious solution here

I have an angular table where table rows and columns are developed from ngfor loop.
As shown in image my table is currently.So when i clicked on save button we need to iterate through each table row and read the values present in each td and need to store them in object.so please tell how to do develop logic in angular.
You can do this using formGroup easily.
See this example,
Table data binding example
Hope this example will give you a better understanding rather than explaining all with words.
I was trying to achieve total using tablesorter for every 10 records shown through tablesorter's pagination.
A question:
Does anyone know how to get data out of angular ui-grid in the currently displayed sorted order?
I found out how to access data out of the grid using gridApi.grid.rows, but those rows do not appear to be sorted per the current sort order applied to the grid.
I feel like the grid is taunting me...showing me data in sorted order, but refusing to allow me to access it! Help!
Have you tried gridApi.grid.sortByColumn(gridApi.grid.rows)?
O Sean that's hot.
But will that re sort the data? Ideally id just be able to get at the data in its already sorted state.
I'm using the Vacuum gem and want to display 12 products per page, but I always get 10 products.
I also tried to use batch code with 'item_search', but didn't work.
Can anyone please help me?
According to this document, ItemSearch returns up to ten search results per page. So, we've to store the result in an array and then process for next page, store the 2 results in previous array, and so on...
Working on showing and hiding comments and by default I show the 2 most recent:
Helper method:
def comments(micropost_id)
Comment.where(:micropost_id => micropost_id).limit(2).order("created_at DESC").reverse
end
2 comments will be show in this way:
Comment 1 (sent 10 hours ago)
Comment 2 (sent an hour ago)
I have a show all comments clickable button which adds all the comments for that particular micropost to the list. This is fine apart from the fact that I need all comments except the 2 most recent.
Using offset(2) takes away the first 2 comments. I basically need to do the opposite of this. So wondering if there is something I can chain onto the offset method to achieve this or if there is a dedicated method to doing the opposite of what .offset() does?
Thanks in advance
Kind regards
You can do as sergio suggests, chop off the last two after you load them from the database or you can reverse the order clause in the query, offset by two and then reverse the result.
I would get all comments from the database and discard the last two in the application code. This makes the query really simple and efficient. Database is traditionally a hardest to scale component, so you shouldn't cause any unnecessary load on it.
