A view is a list of ideas. The ideas can be selected
according to different criteria and formatted in
various different ways. The halfbakery has always
had views; new in version 3.0 is that users can customize
their views and create new ones.|
Creating a View|
The easiest way of creating a view is to take an
existing view, modify it, and save it under a new name.
The next paragraph talks about that.
To start from scratch, go to
Editing a View|
Editable views have  links on
top of the page, next to the view's title
(on top) and name (on the bottom). To edit a view,
select the  link. Most of the rest of this
document is about the page that leads you to.|
Deleting a View|
To delete a view, pretend that you want to edit it and
select the  link on top or bottom of the view.
Once you're in the editor, note that there is a [delete]
link next to the view's name on top. Click on that.
The view's name, if any, is deleted
from the idea: menu to the left.
When a user deletes all views, the initial default
set of views is restored.
The thing being deleted is the way of looking at ideas,
not the ideas themselves. Ideas can only be deleted
one by one, or as a side effect of deleting the account
that created them.
The first section of the view editor lets the
view's owner select ideas that match certain criteria.
Only ideas that satisfy all the criteria are selected.
Criteria are turned on if the check box in front of
them is checked; criteria that are turned off are disregarded
when selecting ideas.|
Filtering by time|
To filter ideas based on the time of their
creation or most recent modification, select the
check box in front of the "Filter by time",
and choose the options below it.
Once the filter is fully parametrized, it forms
a sentence of the form "show only ideas
that have been affected-by-an-event
since point-in-time." You have to pick
the event and the point in time.
The first two options "created" and "commented on or
created by", select the event.
"Created" means just that, the initial entering of
the idea into the database.
"Commented or created by ..." means the idea's creation,
the addition of an annotation, or the addition of a link.
If you want only annotations from a certain set of people
to be of notice, enter their names in the text area below
the "comment or created" line, and change the option
menu to "one of".
If, conversely, you want to filter out annotations from
a certain set of people, change the option menu to
"someone other than", and enter the names of the people
you wish to exclude.
(You will still see all annotations, but they won't
be events that propel an idea into your selection.)
The options after the "since" represent the point in
time after which the event should have happened.
"I last took part in the discussion" means the last time
the viewing user modified the idea or added a link or
In "the end of my last session" and "the start of my
current session", a "session" is any period where accesses
to the halfbakery are less than half an hour apart.
To start a new session, take a half-hour break.
The item below these two lets you enter a specific date,
either absolute, as a day, or relative, as a number of
hours, days, weeks, months, or years.
Filtering by Category|
Check the checkbox in front of "filter by category"
to restrict the categories that your items can be in.
Use the text area below that line to enter the
categories you want to select on (e.g., "Halfbakery: Users"
or "Culture"), one per line.
Switch the option menu to "not in" to exclude the categories
you list, or to "in" to limit the selected ideas to the
category or categories.|
Filtering by Author|
Check the checkbox in front of "filter by author"
to restrict the users whose ideas you would like to read.
List the users in the text area, one name per line.
To limit yourself to ideas of these users, change the
option menu to "by". To exclude users you don't want to
read ideas by, change the option menu to "not by".|
Filtering by Link or Annotation|
Check the checkbox in front of "filter by annotation"
to select or exclude ideas based on their annotations
As above, list the users in the text area, one name per line.
To limit yourself to ideas that these users have annotated
or added links to, change the option menu to "annotated by".
To exclude ideas that these users have annotated, change
the option menu to "not annotated by".|
Filtering by Vote|
Check the checkbox in front of "filter by vote"
to select or exclude ideas based on their votes.
Select the first option, "with ... or more ...",
to limit the view to ideas based on the number of
individual votes. Change the option menu to select
whether you want to filter based on the
number of positive, negative, positive and negative,
or total votes. Enter the fixed number in the
first text field in that line.
The second option, "whose .. total at least ...", lets
you select based on the overall outcome once the
votes are summed up, either scaled to the halfbakery's
-2.5 ... 2.5 scale, or unscaled.
The third option lets the viewer select ideas based
on his or her own opinion of the idea; change the
two option menus to select or exclude ideas you voted
against, for, or that you had any opinion about at all.
Filtering by Name|
Check the checkbox in front of "filter by name"
to select or exclude specific ideas based on their name.
The textarea below the line contains the names of the
ideas that should be excluded or included, one name
Filtering by Search|
To restrict the matching set to ideas that do or do not
contain a specific search expression, select the checkbox
in front of "filter by search". The text field below
that line contains the expression to search for; the search
language is the same as in the dedicated search form.|
Filtering by View|
To build more complicated expressions from multiple view
specifications, check the box in front of "Filter by view"
to use results from another view. (The other view must
The first suboption can be used to restrict the results
of one view to those ideas that also match another
view's filter (A and B), or, conversely, to those
ideas that were excluded by that filter (A and not B).
The second suboption can be used to add the ideas selected
by the second view to those in the current view (A
Sorting and Grouping|
Ideas can be sorted according to up to three criteria,
and are optionally grouped together according to the
topmost sorting criterion.
Ideas that compare equal according to the selected
sorting criteria are sorted alphabetically by name.
To activate grouping, select the option
"by the first sorting criterion" in the "Group ideas"
Sorting and Grouping by Time|
The criteria "modification date", "creation date",
and "your last change" all result in ideas that
are sorted by time, most recent first.
When grouping according to time, a logarithmic
scale is used; the closer a time gets to the current time,
the finer the scale.|
Sorting and Grouping by Category|
Ideas can be grouped by "category" or by "major category",
in alphabetical order of category name. (The "major category"
of an idea is the string in front of the colon in the
Sorting and Grouping by Search Matches|
Select "number of search matches" to sort by
number of matching search phrases, highest first
(similar to the search results in the special-purpose search).|
Sorting and Grouping by Author|
Select "author" to sort alphabetical by idea author.
When grouping by author in the three-column layout
(see below), the selection must be
restricted to some specific authors; showing the
first N ideas of every single author in the halfbakery
just gets too big otherwise.|
Sorting and Grouping by idea name|
To sort ideas alphabetically by name, select this
option. When grouping by name, the actual thing being
grouped by is the first letter of the name.|
Sorting and Grouping by votes|
The "votes" and "votes (worst first)" items sort
by overall voting score, either best to worst
or worst ot best. Select "conflicting votes" to
sort by the number of both positive and negative
votes that an idea received, from highest number
of conflicting votes to lowest.|
The last section of the form determines what the
output actually looks like. The user selects
the overall layout schema, and can then turn on and off
individual fields within that schema. Different
basic layouts allow for different individual fields,
although there are common fields like the idea
name, author, and votes that are possible in
every single layout.
The first layout, a table, is the easiest to read,
most structured. It's quite literally an HTML
table, with each line corresponding to one idea.
(Sometimes I cheat and it's really two lines
corresponding to one item, but don't worry
about that.) The old layout closest to that
was the "high score" table.
The second layout, "an unstructured list of names",
tries to pack as much information as possible into
as little space as possible. It's similar to the
old "recent ideas" layout; a big piece of text
with idea names linked to the individual ideas.
Layout number three, "groups in three columns",
is the default halfbakery home page layout. The
column headings are taken from the grouping criterion
(which must always be on for this layout - one can't
have three columns without group headings).
Layouts number four and five are machine-readable,
not human-readable; they produce the RSS 0.91 and
RSS 1.0 XML files. These don't work with grouping,
since the formats don't have a fixed way of
You can pick how many ideas you see per page,
from between 1 and 100 ideas. In the case of
the three-column layout, the count applies for
each group individually; you'll probably want to
keep it a lot lower than the fixed maximum of 25.
In case of RSS 0.91, the format limits the number
of entries to 15.
If there are more ideas
in the selection than can be shown on the current
page, a small [more] item will appear in the lower
right corner of the HTML layouts,
allowing a user to go to the next displayed page.
Use the browser's "back" button to go back a
page after using [more] to go forward.
View Title and Intro|
Supply an optional title and optional introductory
text below the windowing size in section 3.
A view's title is shown in large font on top of the page.
Below it is the view's introduction, in smaller font.
Long introductions can lead to overly long URLs that
some browsers can have trouble with; keep it short.
Within an intro, the following special macros are
<created> expands to
"Ideas in bold have been created this week."
<changed> expands to
"Ideas with a gray background have been modified
since you were out - that's since date."
work as in HTML.
encloses text that only gets printed if the person
viewing it is logged in.
<last-session-end> expands to the
date of the user's last access before the current
At the bottom of the view editor page, the
view can be given a name. If a view has a name,
the name appears in the idea: menu to the left of
every page; it has the same status as "overview",
"recent" and the other system default views.
A view named x can be accessed as
https://www.halfbakery.com/view/x by its
owner. (You have to be logged in for this to work.)
If a view doesn't get a name, it can still be
seen; but it's up to you to remember and reuse the
URL that points to it.
