Hi,

I am new to eLog, trying to make a logbook tool.  This is probably a question with a simple answer, but here it is...  I need to be able to edit the entry time for an entry as it is being made and also in Edit mode later.  We have field staff who use a paper log in the field and then come back to the computer later and create the log entries, and they need to be time stamped to reflect when an event happened, not when the entry is put into the log.

I'm guessing I'm missing something easy in my Config file, I've looked through the config examples and searched the forum but I couldn't come up with an example of how to make this work.

Thanks in advance!

Jay

Hi Jay,

the entry time cannot be changed, because it should reflect the real time when the entry was made. What you can do in your case is to define a "datetime" attribute, which contains then the time stamp. You need something like this:

Attributes = Author, Field time, Subject

Type Field time = datetime

... 

 Hi, Stefan,

Thanks for the quick reply, I've added that to my config and it does what we need.

Cheers, Jay

Hi,

I love this software. I am not a programmer but have learned alot about the program.

I have 2 questions.

1. when i do a reply it will bring the original qutes with it but i have the option to change what had been entered. once i do the reply and reply to the reply i can not change the first reply but can change the second reply. This just started last week and i am not sure what has changed. i even uninstalled and reinstalled. If I try to just the HTML i tcomes up with code? If I do elcode seems to do ok just not able to stop the editing of the the last reply. Plain seems to do the same as ELcode.

2. I have also had trouble with E-Log not starting on my XP machines. Any ideas?

Thanks for sharing such a powerful program it is sweet.

Kyle

Sorry but I don't get your point. See I modified your original entry above. Now I will submit this entry, and do another reply.

So this is my second reply. I can edit both your original entry and my first reply. 

Your point 2) is too unspecific. I need more information there. You could run the elogd daemon interactively and check if there is any error output in the console window.

Hi

I have a logbook including the attributes: Author, Topic Date, Phase, Reference, Subject, Start Time, End Time, Duration

The Phase attribute has a number of MOptions including: Design, Manufacture, Testing, Results, Transport

I only want the attributes Start Time, End Time, and Duration to be shown if the Transport Phase is selected. I have tried using the conditional attributes

MOptions Phase = Design{1}, Manufacture{1}, Testing{1}, Results{1}, Transport{2}

and

{1} Show Attributes Edit = Author, Topic Date, Phase, Subject, Start Time, End Time, Duration
{2} Show Attributes Edit = Author, Topic Date, Phase, Subject

This works to show the attributes when the relevant Phase is selected but the Edit page shows the Phase options including the {1}/{2}. Is there are way that these conditionals are not displayed?

Also, I would like the "Duration" Atrribute to be a calculated value showing the time difference between Start Time and End Time. Is this possible?

Thanks,

Adam

The conditional attributes work only with Options, but not with MOptions as written in the documentation. I tried your set-up with Options and it worked ok. If you attribute Phase is non-exclusive, meaning it could be Manufacture and Testing at the same time, then you have to play some tricks with an additional attribute like

Attributes = Author, Topic Date, ..., Duration, Transport

MOptions Phase = Design, Manufacture, Testing, Results, Transport

Options Transport = Yes{2}, No{1}

{1} Show Attributes Edit = ...

{2} Show Attributes Edit = ...

On the matter of automatic calculation of fields, it is possible using included javascript but you have to do the work yourself.  For example, we have a log which computes responsivity as the ratio of a photocurrent and optical power.  With log attributes called "Photocurrent", "Optical Power" and "Responsivity" there is a file in the logbooks directory called photomixer_javascript.html containing something like:

<script>

if (document.form1.Photocurrent) {
  document.form1.Photocurrent.onchange = new Function(
    "mod();"+
    "var power = parseFloat(document.form1.Optical_Power.value);"+
    "var current = parseFloat(document.form1.Photocurrent.value);"+
    "if (!isNan(power) && !isNan(current) && power != 0.0) {"+
    "  document.form1.Responsivity.value = Math.round(current/power*100)/100.0"+
    "}"
    );
  document.form1.Optical_Power.onchange = document.form1.Photocurrent.onchange;
}

</script>

and the elogd.cfg file includes

Bottom text = photomixer_javascript.html

for the relevant log.

The assignments to the onchange handlers are guarded because this javascript is included on all pages for that log, including the list pages where there is no such field as Photocurrent, (or Optical_Power) and the event handler function is defined dynamically for the same reason.

Using the Windows event log won't help much. I guess in your case elogd is driven into some kind of endless loop (does the CPU go to 100%???). There are only two possibilities to tackle this:

1) You find a way to reliably reproduce this problem, tell me how to do this. When I can reproduce it here, I can fix it easily.

2) You do debugging yourself. Under Linux this is simple, since you have debuggers on most systems. Under Windows however, you first have to install the Visual C++ development environment. I believe there is a free version (Express?) which you can use. You then run elogd under the debugger, and when it hangs you investigate where. This needs some basic knowledge about C++ development and I'm not sure if you have this, but maybe you can find someone around you who does.

Sorry about the multiple entries!!! -> browser problems

Hello !

Is any posibility to  set  quick filter, for fields with atribute "date", to exactly value, like 15/07/2009, instead of drop menu with values like - last day, last week, etc ?

Tnx in advance ! 

No, this is not imlemented. But you can go to the "Find" page, and select the "Start" and "End" date with the calendar picker tool. This are a few more clicks to do, but puttting this all into the quick filter would not fit there. 

 ok, tnx. 

Have a few issues here. The big one is that I have some users of our elog books
that are in India, while the server is in USA. When they click on thumbnail images
then press their browser back-button they get a page expired message and are
unable to see what they were looking at before unless they go back to the main
page. Is this an elog problem or something with Apache?

Also when these users in India write messages sometimes we end up with
duplicate messages seconds apart. I'm not sure if they are pressing the submit
button repeatedly or pressing their browser back button. I've suggested they
try not to do that.

Last issue, is there a way to make thumbnail images open in a new window
by default rather then the same window? This would help fix the first issue at
least. Is there some setting to fix the page expiration/time-out issues?

Regards,
Mike

That's strange. Normal pages are set to "pre-expire" (expiration date 1983...) which forces the browser to always load them from the server. This is necessary since someone else could have modified that page and you would look at an old page in your browser's cache. But using this, I never saw a "page expired" message. The browser simply reloads the page. Maybe if the internet connection got lost in between and the browser cannot load the page from the server, you have a problem. Attached pictures have a expiration date of +1 day. So even if you span different time zones, that should be fine. Can they try to access https://midas.psi.ch/elogs/Linux+Demo/14 and see if they get the same problem there? This is my demo setup and resides in Switzerland.

The only way to get two entries is if you submit your entries twice. The same problem exists on some credit card payment sites, which explicitly state "please be patient, don't press submit twice, don't press back". The same applies for elog. 

No, this is not implemented right now. But if nothing else helps, I can add a new option.

 Stefan,

Thanks for writing back so fast. I'll have the folks in India check that link and see if the problem exists there.
I couldn't duplicate the problem here on my end. I'm beginning to think that it's a connection problem. They
tell me that the elog site (our site) is slow for them. It's only capable of 118kb/sec which, coupled with
the distance from USA to India might make things slow. In the USA I found the site to be usable and not that
slow. I'll let you know what they say about the test link.

Mike

 Stefan,

I talked to my associate from India. He tried that link you provided and claims that even on your
site the "page expired" message occurs. Weird eh? Any ideas?

Not much. Since they are the only ones reporting this problem, I'm tempted to attribute this to their local configuration (browser, proxy, etc.). Have they tried different browsers on different machines?

 I think you are right. I suggested those things to them. I believe this issue is closed here.
